For those who interested why their Diagonal Step Sequence (DiSt) was called level 1, I did a small analysis.
Main points:
1. Their DiSt was a second step sequence in the dance so, according to the rules, the steps and turns were considered according to Style B ruqirements.
2.
Level 2 requirements for each partner according to characteristics of levels Style B are:
Step Sequence is not interrupted more than 25% of the pattern in total, either through Stumbles, Falls or any other reason
AND
Footwork includes at least 3 different Types of Difficult Turns (one of which being a Twizzle or Double Twizzle)
AND
At least 2 Change of Hold is included
AND
At least 2 different Dance Holds are included.
So to get level 2 you only need to have two different holds in StSq, with two change of holds. For ice dancers of top level it's not difficult at all.
There are only 6 types of difficult turns: rocker, counter, bracket, choctaw, outside mohawk and twizzle. So to get level 2 you need to execute cleanly AT least three of them. To get level 4, for example, you need to cleanly perform 5 types (including double twizzle).
According to ISU rules difficult turn is called 'clean' when:
1) entry and exit edges are correct (there should be a visible tracing of the curves);
2) the turn is not jumped or scratched.
If the turn is flat, jumped or scratched, the panel count it as simple turn. And very important:
the depth and quality of edges is NOT RELEVANT to give credit to a difficult turn. It is assessed by judges in the GOE only.
So, let's see how many clean difficult turns each of them executed:
Maia: she intended to do BRACKET-CHOCTAW-COUNTER-TWIZZLE-ROCKER.
Bracket - was ok, not very deep but clean.
Choctaw - it was not a clean turn. If you will watch it in slow motion (I used 0.25x speed) you will see that she starts it with very deep inside edge but right before the change of foot her blade is going flat (at 4:16, they skate on fat blue line), then she puts her free foot on the ice on clear outside edge. The camera agle is not very good, unfortunately, to say for sure, because in the moment of the step Alex comes in front of her and we can't see her feet. But right before he hides her you can see that the edge is flat. Tech panel can see replays from different cameras, so they've seen it for sure.
Counter - in slow motion again you can see that she uses the toe of her free foot during the turn. So not clean too.
Twizzle - they do twizzle of two and half rotation. Clean.
Rocker - not clean. Again the same mistake: the edge is deep at first, but then it goes flat before the turn, the exit is not clean too. More than that, she jumped in the moment of turn (in slow motion you can see it at arounf 4:30).
The rest of the turns and movements are just a transitions, no more difficult turns attempted.
Alex: he tried to do BRACKET-ROCKER-COUNTER-TWIZZLE-CHOCTAW.
Bracket - clean, better than Maia.
Rocker - it's hard to say, but it seems like he helped himself with free foot too (like Maia did with her Counter). He did Rocker when Maia did her Choctaw, so you can wtch it yourself maybe I'm seeing things (but you need to watch in slow motion of course). Other than that the turn seems clean, the exit edge is very light but visible. So let's call the turn questionable.
Counter - seems like the flatest turn of the whole sequence. Not clean.
Twizzle - ok. Clean.
Choctaw - questionable again. The exit edge was scrapped, the quality of the video is not good, so I can't say for 100% sure. You can see it yourself (at 4:31).
So what we have in total:
Maia - 2 clean types of difficult turns (Bracket and Twizzle) + questionable Choctaw.
Alex - 2 clean types of difficult turns (Bracket and Twizzle) + questionable Rocker + questionable Choctaw.
So even if panel counted one of the steps I called 'questionable', or both questionable steps in case of Alex, the Step Sequence should still be level 1. And only if all questionable steps would be counted, then Step Sequence would be level 2
at max. Don't forget, the panel have replays from different angles.
Holds: they had Killian - Waltz - Killian - Waltz - Killian - Foxtrot. In total 3 types of holds with 4 changes of holds. Enough for level 4 style B step sequence. And it absolutely
DOESN'T matter for the level of an element how close their holds are, because the 'closeness' should only be assessed by judges IN GOE AND PCS mark (Performance/execution).
So, I think level 1 call for their DiSt in this case is correct. But the main reason of that is poor quality of their steps, not the lack of holds or quality of their holds. The poor quality can be explained by tiredness (start of the season, end of the dance), or by lost focus, ot by the combination of both.
The more forgiving technical panel would probably call it level 2, but higher level for this sequence is impossible.
However, with clean steps both Maia and Alex would have 5 difficult turns each, and the requirements for level 4 will be met.

P.S. I usually don't do this kind of analysis because it takes too much time, and they are kinda subjective at times. So if anyone disagree with me on some points, please do tell!
