Relative difficulty of types of jumps: triples versus quads

I'm surprised 3Lo was the first triple.

I wonder if the difficulty feels different for men versus women. I can only comment on women since thats what I watch. I will do so now.

For triples we have the following order:

3T
3S
3Lo
3F
3Lz

3Lz seems to be the only one that consistently trips up the top girls, even the ones who jump quads.

The only girl I can find who clearly prefers the Lutz to the flip is Sadkova, see the following:

You can also decide what the following means to you in regards to Agaeva:

Muravieva is the only example I can find who actually has a better success rate with the flip than the loop (I'm looking at all the top girls since Zagi/Medo era):

T6bVnX6.png

So for triples the Lutz is clearly harder than the flip, with 1 maybe 2 exceptions, and Muravieva the black sheep with the flip/loop disaprity. I would say the trend generally holds for novice, junior and senior alike (I'll touch on this at the end). This is notable because it seems to me that is NOT the case with quads.

Now about quads, the fun part...

For Seniors (or generally mature/grown girls):

4T
4S
4F
4Lz
4Lo

For Junior (moderate maturity):

4T/4S
4Lz
4F
4Lo

For Novice (small girls):

4S
4T
4Lz
4F
4Lo

About the 4Lo, we can just forget about it. Its very obviously the hardest. I think Adeliia is the only one to land it in competition, and its been a while. Not exactly consistent either:

TdnCAJb.png


For seniors, 4T seems to remain the easiest as with triples. Its the only quad Kamila and Akateva maintained after growing. Adeliia, Sadkova, Sasha, all also showed it. Notice also how they all stabalized or otherwise improved it as they aged and grew. Is there a quadster who can't jump a 4T? Gorbacheva with the 4S is the only one I believe. Wait... Anna only had a 4F and 4Lz! So strange! What an interesting skater... The only one who jumped quads, but not a 4T or 4S, everyone else has at least either or.

4T also seems to be the jump girls who never jumped any would speak about when suggesting future quads; I've heard Frolova mention trying 4T, and Sinitsyna maybe too (this was when they were extremely consistent, fighting for bronze)? Among others...

4S is a close second, we have: Akateva, Sasha, Valieva, Gorbacheva. However, again, the former 3 also have the 4T, so its a clear favourite, and this will become especially significant when we analyze juniors and delve deeper into the quality of these jumps in regards to age of the performer. The raw correlation here is not particularly significant but still real.

The 4Lz vs 4F is very interesting... Sasha never jumped flip combos, Anna jumped one, however their solo flips had higher landing rates than the solo Lutz despite them jumping it less. Landing means not falling, nothing about edges or rotation. Here are the two athletes respectively:

6KIE128.png

Consider also Adeliia has a semi-consistent flip but never landed a Lutz... If we consider Dvoeglazova though who is borderline senior, she has a pretty consistent Lutz with no flip (though she landed it in training). So which is harder?? If it weren't for Dvoeglazova it would seem the flip is more manageable based on landing rates. Everyone calls Dvoeglazova a "true senior", however since she never actually skated senior competition and a LOT can change in a year, I am going to leave her out of this discussion. Considering the landing rates of the former champions, and Adeliia's repertoire, I'm calling the flip slightly easier for the quad (IN SENIORS), so keeping the same pattern as the triple but with an almost nonexistent gap whereas the triples had a conspicuous disparity. It is noteworthy that the two approach equilibrium when adding an extra rotation.

So, not much else of interest when comparing triples and quads with the ladies, other than the sudden explosion in difficulty for the loop and the Lutz-flip equilibrium. Another user suggested the loop should be easier if the calling was more strict with the Lutz and flip. I disagree, at least for ladies. Its clear almost nobody can even rotate a loop in any way, while the Lutz and flip, although perhaps often dirty, are clearly doable and what they are supposed to be. For men, maybe there is a rule change which would change things, I dont know.

However, the interesting observation with relative difficulty is not between the triples and quads, but in regards to quads between age groups (at least for ladies).

It is hard to group by direct discipline (senior, junior, novice), since there is a lot of overlap, so I am just going to generalize by apparent physical maturity and size. We can quickly start with Rita and Kostyleva, the famous little quadsters:

3us9Bpm.png
ur54RFp.png


To list all the 4S specialists under seniors would take FOREVER, I'll go off the top of my head just quickly: Andreeva, Korchazhnikova, Tsipukhina, Titova, Streltsova (#1 novice currently, I think she has a 4T but the 4S is way better), Gorbacheva (when she was junior), Gordeeva, Milto, Mazur, Stotskaya, Lukasheva, Pleskacheva (is trying), Lebedeva (last year), Zhilina (also has 4T), etc...

UkPLYEt.png


The only exceptions I can think of are Prineva and Sadkova, neither of which had consistent toeloops (Sadkova's is stable now, that she is bigger and older). Meanwhile a lot of the Salchow girls are quite consistent. Anna Dokukina has a 4T, I think Sarycheva landed a 4T in novice recently, Zaikina too? Anyways, the preponderance of 4S is enormous with younger girls; the roles are reversed between older girls and younger girls with the 4T/4S. Whereas 4T was the winner with seniors, the younger girls massively prefer the 4S. The bigger and more mature they are the more they lean towards 4T.

Kamila's 4T was probably the best we've ever seen from a woman during that 22/23 season, wow, just gorgeous...



Again Akateva is almost fully rotating that 4T after gaining a lot of size; I think the 4S is gone forever:



When we look at the older/taller juniors it starts to even out right in the middle. We see Dzepka and Dvoeglazova with 4Ts on the podium this year. Its a very smooth correlation shifting from 4S dominance to 4T dominance with age. Gorbacheva is the only senior holding on to the 4S and shes tiny.

Sasha did stabilize the 4S later into her career, but interesting thing is she was already racking up 4S attempts in 2017, 2 years before consistently incorporating the 4T.

PTlRdrT.png


Kamila and Akateva are slight exceptions in that they tried the 4T before the 4S in competition, but these two (especially Kamila) became total 4T specialists. Considering again they lost the 4S but hugely improved the 4T (especially with Kamila where it got more beautiful each year), I think this trend is quite ironclad.

Another really interesting correlation is that we never see the 4F from young girls, despite it supposedly being easier for seniors. Return to the earlier Sasha/Anna screeshots and notice the 4F was jumped once each in 2019 while the Lutz was there in 2018, and after 2019 the flip became more landable as they got older. Adeliia only started jumping the 4F in 2023. We have Prineva trying the 4Lz in juniors right now, but nobody with the 4F. Dvoeglazova just starting to try it in training as she enters seniors, but only landed 4Lz in competition. As far as I am aware, nobody has ever tried a 4F below seniors. Sasha and Anna were considered seniors in 2019. Nelyubova and Lukasheva also both tried lutzes (in junior), but never flip!

If we consider the entire female competition then as a whole, across all age ranges (which I think is unwarranted given what we have discovered here) we can actually suggest the Lutz as greater plausibility than the flip when both are rotated quaruply, despite the conspicuous opposite property of their triple versions. Although again we do see the equalization of the two in any case as we enter the quad realm, which is interesting (maybe its because technique becomes less relevant? Just get the rotation out and you win, since nobody else is even trying?).

In conclusion:

The women's triple difficulties are a borderline rule with the Lutz as most problematic, and flip following, over the loop, which is very clear of a salchow, and the solo 3T is easiest being almost never failed. Only Sadkova and Muravieva show exception, maybe Agaeva too depending on how you look at it.

When we look at quads, senior women have a massive preference for the 4T, with the 4S a moderately close second though the gap is real. Looking at younger girls, we see a preponderance of 4S with 4T in second however the gap between both being way bigger than in seniors, and with this reverse correlation. We find it to be a smooth transition towards 4T when considering a large data set including the older teenage girls who are transitioning into young ladies looking forward to soon-coming senior competition. We see that especially size and physical maturity lend themselves to the 4T, with girls jumping their most beautiful 4Ts when they are at their most developed.

We find also an age disparity between the 4F and 4Lz, with the 4Lz being present in young competition but the 4F completely absent, meanwhile the 4F is slightly preferred in seniors to the Lutz.

When comparing with their triple counterparts, the 4F and 4Lz gap equalizes with the Lutz being a virtually exclusive preference in combos for Sasha and Anna however the solo flip being a more successful jump than the solo Lutz. Adeliia also jumps the 4F without a Lutz. Overall if we consider senior competition the flip still seems more stable despite trending towards equilibrium with the Lutz. If we ignore age-correlation we find the Lutz becomes preferred to the flip, contrary to the extremely strong disparity when assessing triples. Again, in any case the flip and Lutz equalize for quads despite that extremely strong disparity for triples, which is significant and interesting.

We see the 4Lo is almost completely absent from female competition barring Adeliia Petrosian, despite the same sort of jump being standard as a triple.

Some analysts suggest a change of rules might affect these patterns. The loop pattern will not be affected in female competition by slight rule changes. The age correlation is also obviously independent of rules changes. The lutz-flip correlation could be affected by rule changes if the lutz becomes less desirable as a combo entry, however the sudden equalization of landability between the lutz and flip from triples to quadruples will still exist, which is interesting.

Of course those same analysists might be speaking about men's competition specifically, which does not matter to this discussion, and they might be totally correct in that regard.

A slight addendum: we do get more exceptions to the triple lutz-flip rule when we look at young girls. The lutz still gives more problems but not in such a drastic manner. We can check a couple examples.

Rita pretty much doesn't even jump the flip. She likes the Lutz a lot:

K0afZOY.png


Prineva leans similarly:

wahksBk.png


Tsipukhina doesn't like the flip:

e1RH2FI.png
7WtRyMq.png


The rule is still pretty strong for juniors actually as I look through all the juniors, the majority lean towards the flip, although a lot of them are somewhat borderline and the correlation isnt as jarring as it is with seniors (but still real and clear). We can see above that it was easier to find exceptions as well whereas in seniors Sadkova is sort of a weirdo! It just adds a little bit of weight to the junior-specific 4F 4Lz observation we made earlier.

This is a Glenn 3Lo. Huge prerotation before she has left the ice. There's actually only two rotations there but they counted it as a triple.

Given she's travelling diagonally along the ice, it's nearly one full rotation before she's even left the ice.

Glenn3F.gif

This is a sufficient jump, not as bad as you're saying. I've looked at it from another angle as well. She leaves the ice with her skate facing the short board, perhaps a few degrees past it, and her landing is a little past the skate facing the long board, aka making it to at least the 1/4 turn mark.

The points system promotes good Lutz jumpers starting from an early age. I recall an interview with Vincent Zhou, who was more of an edge jumper himself, saying how the 3Lz was such an important jump in juniors. The result is that you're going to have a higher proportion of proficient Lutz jumpers among top seniors.

That could definitely play into it. Zhou did not have textbook Lutz/Flip technique, however. It's very doubtful he'd ever be able to do those quads without using his toepick to turn so much on the entry, and also if he was asked to do a deeper outside edge on the Lutz.

Mechanically the Lutz does have the potential to generate more power, using 2 legs instead of just 1. Compared to a Flip there is a little more of a height potential too, because you can press hard onto the edge for a Lutz, in a way that isn't really feasible for a correct-edge Flip. Still, doing a correct edge Lutz is more difficult on average than a correct edge Flip.
 
By the early 1970s most top men seemed to have 3T, 3S and 3Lo, some had also 3Lz and 3F. 3A was attempted by a few skaters by 1978 when Vern Taylor hit it. Taylor was possible the first to get all six triples by 1980. And from then on having all six started to become the norm.
Well, it took a little longer than that.

3A was still pretty rare in the early 1980s. And even those guys who could do it couldn't beat Scott Hamilton, who didn't have a 3Lo either. (At least not overall, because of the figures.)

By the mid-1980s, it was more common for medal contenders and others for whom jumps were a strength to include six different triples. But there were still plenty of senior men at Worlds who weren't attempting all of them. There probably wasn't a clear majority who were until after the figures era.

Thank you for that observation. I always thought that Boyang Jin had a spectacularly deep outside Lutz edge -- the only one that visibly deepened as he approached take-off.

Here's Dona;d Jackson in 1962 (first triple Lutz). The counter-rotation that he gets is astounding.

No way. Body is 3/4 prerotated (ouch I hope she has a good physiotherapist for her back! :(). I won't go into the landing or the jump itself which is massively off axis, landing completely on the front of the blade barely holding on. This isn't a once off it is almost always illegally prerotated.

Unfortunately math is pointless,,,
Statistics (that "dismal science" -- oh no, that's economics) may be pointless, but real math -- oh no, we can't understand esthetics without it. As we were saying on the other thread, about the Fibonacci numbers and the golden ratio, this is all about the definition of mysterious beauty (as in Nina Petrokina's free skate, that I just saw on the little big screen :) )

These magic numbers, re-discovered in 1202 by Leonardo of Pisa (son of Bonacci), actually go back to the religious poets of India in the fourth century BCE. They sought a mathematical formula that would govern the total number of possibilties of short syllable/long syllable sequences in Sanskrit poetry.

The golden ratio (aka divine segment, etc.) that the ratios of successive terms of the Fibonacci sequence, convene to, is associated with the Pythagorean school (6th century BCE). The Pythagoreans were math mystics who were fascinated by the magical and occult powers of numbers and geometric shapes. Their favorite was the pentagon. The golden ration (1+sqrt5)/2 is the ratio of the diagonal of a regular pentagon to its side.

According to @4everchan :rock: this dictates the optimal point at which a figure skating short program should hit its musical and choreographic climax for optimal esthetic and emotional effect (about 62% of the way though the program). I am at present hard at work viewing famous and effective short programs of the past to tie check this out. :slink:

She probably has the best quad of all time. There's one I posted of her at the Moscow stage doing a huge 4T in warm up that was at age 17 last season (I'll try to find it). People like to say she lost her quads last year, but that's not true she had about a 50% success rate just didn't happen to land one in the three events she competed in but landed several in warm ups. Shimada has much less than 50% success with landing and fully rotating her quad, and there was a period where she went I think 6 out of 7 events where she failed to land a clean 4T when attempted, but no-one was saying she's lost her quad :shrug:

I read something about Shcherbakova being more of a right footed skater so favoured the 4F and 4Lz it was easier for her, whereas Valieva and Akatieva are left footed so favour the 3A, 4T, 4S. Interestingly Adelia must not favour one side over another.

I wonder if the loop is just harder because it's not worth investing your time into a jump that won't be used in a combo. Jumps like the lutz get prioritised throughout the years in training.

Unfortunately math is pointless if people are adding up incorrect data. The amount of heavily pre-rotated fake quads that get counted as real makes protocol-collecting data mostly pointless, for people who are interested in real skating and mechanics.
We can say the same about heavily prerotated fake (your word) triples and fake doubles (plenty of illegally prerotated doubles in combos). It skews the data. Even if there is some prerotation in a quad, I think that is some what acceptable given the difficulty, but there should never be any lenience at all for a much simpler jump like a triple or double being prerotated.

4T as a 17 year old with a couple of 2A's on the end as well. Perfect 4T technique. I don't know what a fake quad looks like but it's certainly not like that.

That is not 3/4 of a turn, but even if it was, this does not tell the whole story. What matters is where a jump lands in relation to where it left the ice. Exactly as I said, her skate is facing the short board of the rink at the end of the image here. From that point she needs to land at least 1/4 turn more around, and she does. I've looked at her other 3Loops and they are past the 1/4 mark too.

The other things you tried to say are irrelevant to measuring rotation, but actually a jump being tilted (while not desirable, per se) can help someone to get a bit more rotation, as it creates more space in the air before the skate lands.

well.. that's not exactly what i said LOL :) but it's okay :) I was merely giving an example :)
 
Yeah, the awful modern-day lutz technique is a big part of this. Flopping edges prior to taking off is such a copout. Although you can still occasionally see an old school proper lutz with a sustained, deep outside edge-- Julia Sauter at Europeans did a great one in her short program.

Honestly, I think loop, flip, and lutz should be roughly the same value. Particularly considering how closely linked the lutz and flip are -- many skaters are doing the same jump with negligible differences in both takeoff edge and entrances.
 
She probably has the best quad of all time. There's one I posted of her at the Moscow stage doing a huge 4T in warm up that was at age 17 last season (I'll try to find it).
Valieva's 4T is the best quad quite easily. I remember a jaw-dropping attempt at one of the jumping tournaments, I do not know if it was 23' or 24'. It was the one I was hoping to find.

Even if there is some prerotation in a quad, I think that is some what acceptable given the difficulty, but there should never be any lenience at all for a much simpler jump like a triple or double being prerotated.
Stop. You are universally subjecting athletes to consistent rules and logic. Enemy of the sport.
 
well.. that's not exactly what i said LOL :) but it's okay :) I was merely giving an example :)
Actually, I did spend some time studying Michelle Kwan's Romanza program at 1996 worlds in the light of your posts on the subject. Her "climax" is a little late (but there are two different pieces of music space together.) If nothing, else, it made me better aware of how musical development and figure skating choreography can go together. Thank you.

I've added some more notes to the screenshots to help you.

Amber-loop-frames-by-frame-Copy.jpg

Then with the landing there's a real twist of the blade the screenshot doesn't quite capture it. Whatever you think of the landing, the jump is still heavily prerotated it's just a question of whether it should get a q as well.
Amber-3-Lo-Landing.jpg


It's definitely a cheated jump. One judge even gave this jump a 2! Sakamoto also does something similar with her whole body when jumping the flip and lutz. I will investigate this later on.
 
Here's Dona;d Jackson in 1962 (furst triple Lutz). The counter-rotation that he gets is astounding.

Thank you for posting, it's beautiful :clap:

People who fuss about edges nowadays forget the whole point of the edge in figure skating: the edge is not about a tilted foot as such - it's about the curve that tilting provides the skater's trajectory with. "A deep edge" means a deep curve in the trajectory. It can be easily seen by an unarmed eye an it is impossible to cheat.
The modern-day Lutzes that are jumped from almost a straight line after a slight last-minute tilting to "the Lutz side" directly illustrate the decreased importance of skating skills in favor of a formally executed acrobatic element. Alas, that's what skaters are rewarded with points for.
 
The rotation of a jump is measured by when the blade leaves and returns to the ice, not by the body position.
Meaning the moment there is no longer full contact between the entire blade and the ice, or the last moment at which any part at all (usually the pick) has contact?

@uwoawuwoa these people have no idea what we've been through...

The technical panel handbook doesn't specify in writing.

What it does say:
The quarter/half mark of landing are the border lines to identify cheated jumps.
The camera angle is important to consider when deciding upon a cheated jump particularly when the jump is at the opposite end of the rink than the camera.
In all doubtful cases the Technical Panel should act to the benefit of the skater.

and also

A clear forward (backward for Axel type jump) take-off will be considered as a downgraded jump. The toe loop is the most commonly cheated on take-off jump.
The TP may only watch the replay in regular speed to determine the cheat and downgrade on the take-off (more often in combinations or sequences).
