I believe RH mentioned they didn't understand which missed step (or edge missed) justified a level 3 on 1 of the step sequence but I don't which step sequence he is talking about.
I think their performance value was very good in the SD tbh because missing a level on a step sequence is not visible to most untrained eyes so it really doesn't impact the PCS (perf, interpretation and transition) hence those high PCS. The twizzles but specifically the one is missed was a bit more visible but still it was not a stumble of even a balance check, otherwise the rest of the twizzles looked good so once the level is downgraded high GOEs can be awarded. Anyway, P/C have said in interviews they take full responsibility for their shortcomings in the SD and that blaming the judges is not right, looks like they're more mature than their own coach, good for them.
I would just say this about V/M's FD, a stumble on the contrary to missed levels is a very visible mistake which does take away from the performance and disrupt the flow of the program, which, compared to singles, is at the heart of an ice dance performance, so it should definitely be reflected in the PCS specifically in the Performance and Transition (as it happened on a transition and not on a step seq). So I did expect lower PCS. Scott also had a quite wobbly first twizzle and they kind of travelled apart on the second set. Basically, their twizzles sequences was tense. I mean they performed this FD much better at GPF and NHK. Their world perf was tense and not up to their standards like P/C's SD was not up to their standards.
Basically, I think the results are fine in the end, but I thought V/M's Fd could have been more in the 114/115 range but as you said we are no judges or tech panel.
Both teams have the motivation to start the season. They're great champions and seems to get along.
