When the 4A still had a higher BV, it was attempted once, by Artur Dmitriev at the Russian Cup Final in February 2018. After the new score was used, it was attempted by Dmitriev 3 times and by Hanyu twice. Malinin has now 11 4A attempts in his pocket.
The number of skaters who have revealed that they have at some point trained is also quite low, 6: Kurt Browning, Elvis Stojko, Alexei Yagudin, Brandon Mroz, Brendan Kerry and Keegan Messing. There must have been more, but hard to know if they don't talk about it.
The 4A is surely the most difficult jump at the moment, but now that it has been cracked, I could imagine that in some time there will be others who will start working on it and attempting it in competions also. It will not happen right away, but let's wait and see.
Thinking of the scoring of quads, I actually think the current system actually encourages quads. This is obvious when you look at their history. From the first attempt until 1996, the quad was a marginal element, attempted by some, but not something that everyone strived to get. Something changed in judging before the 1996-7 season, because that season marks a change with more pops and poor attempts than ever before. In addition to the 4T and 4S, 4Lz and 4Lo were attempted. The increase in attempts and skaters attempting quads continued until the start of the IJS.
That was followed by stagnation that lasted until the early 2010s. This is IMO because the jump scoring was pretty harsh under the early IJS. A poor attempt was more often than not deemed downgraded - no underrrotation until 2010 - and you would end up with a very low score for your efforts. The BV for 4T for example went up from 8 to 9 to 9,80 from 2003 until 2010, but that did not encourage skaters to attempt more of them, actually the number of attempts went down from 164 to 129. Though the BV was higher, the negative GOEs got factored with 1,60 so that getting a very low score was even more likely than before.
The big overhaul starting with the 2010-11 season introduced even higher BVs BUT more importantly also underrotations in addition to downgrades. It encouraged risk-taking considerably compared to early IJS. In addition, two quads in the short were allowed which made having multiple quads also worthwhile. This change started to get results, ie more attempts, more skaters attempting quads and also attempting multiple quad types only a few years laters, starting from roughly 2014-5 onwards.
Since then the scoring has gradually gotten harsher again, but that has not been enough to discourage more skaters going for quads.
This table shows the changes in 4T and 4S scoring in the IJS period.
| Period | 4T BV | GOE | Min | Max | 4S BV | GOE | Min | Max |
| 2003–04 | 8,00 | +-3 | 5,00 | 11,00 | 8,50 | +-3 | 5,50 | 11,50 |
| 2004–08 | 9,00 | +-3 | 6,00 | 12,00 | 9,50 | +-3 | 6,50 | 12,50 |
| 2008–10* | 9,80 | -4,80–+3 | 5,00 | 12,80 | 10,30 | -4,80–+3 | 5,50 | 13,30 |
| 2010–15 | 10,30 | +-3 | 7,30 | 13,30 | 10,50 | +-3 | 7,50 | 13,50 |
| 2015–18** | 10,30 | -4,00–+3 | 6,30 | 13,30 | 10,50 | -4,00–+3 | 6,50 | 13,50 |
| 2018–23 | 9,50 | +-4,75 | 4,75 | 14,25 | 9,70 | +-4,85 | 4,85 | 14,45 |
*Negative GOE multiplied with a factor of 1,60.
**Negative GOE -1 and -2 multiplied with a factor of 1,2 and -3 with ca. 1,33.
Thinking still about the history and how the jumps get done in reality, I think that the order of difficulty should be this: 4T, 4S, 4Lz, 4F, 4Lo, and 4A. I would like to see the BVs also reflect this.
The 4Lz was the third quad type to get attempted already starting from 1995. It is also the third most common quad type attempted - more than 900 attempts in the IJS era (almost 9000 for 4T and 4100 for 4S). Its history and popularity indicates that it is perhaps not that difficult and that it could be regarded as slightly overscored.
The order of 4F and 4Lo is just about interchangeable, the 4Lo got attempted in the late 1990s, the 4F only in 2010, both were first landed in 2016. 357 flips and 313 loops have been attempted since 2010. The 4F gets put into combos these days, but 4Lo combo is still a big rarity. I say give more points to these two jumps, they would deserve some encouragement.
Btw, a 0.00 GOE quad is already a pretty good one. The stats for this fall so far in order of frequency
4T 680 attempts, average GOE -0,72, 315 or 46% got 0,00 or higher GOE
4S 409 attempts, average GOE -0,62, 192 or 47% got 0,00 or higher GOE
4Lz 129 attempts, average GOE -0,50, 61 or 47% got 0,00 or higher GOE
4Lo 48 attempts, average GOE -0,93, 17 or 35% got 0,00 or higher GOE
4F 31 attempts, average GOE -1,10, 13 or 37% got 0,00 or higher GOE
Somehow I find it unlikely that a high BV on its own would be enough to encourage attempts for some jump type. There are so any factors to consider and different skaters have very different sets of motivations... I hope Malinin stopped complaining about the low scores of the 4A and would concentrate on showing with his jumps that it is possible - that is probably the more important motivation for others to follow him than the individual scores.
