A couple of thoughts:
I really wish Akhanteva/Kolesov got a new free skate. They're already not the most interesting pair and Shine On You Crazy Diamond does them absolutely no favors :noshake:
I enjoy Artemeva/Nazarychev quite a bit, but man they sure struggle with that throw flip a lot. I noticed it last year, but her rotation on it is SO delayed, that could've been what caused the big issue today. Still really like them (and that ridiculous free skate) a lot though!
I guess Akhanteva/Kolesov had even less time than other pairs because they had some sort of drama in the off season. According to the Russian forum, they broke up the partnership (not sure for how long) and didn’t skate and then again got back together... so that would have impacted on their decision to keep the program because they didn’t have much time. I don’t particularly love the program, I find it boring, but I think Akhanteva/Kolesov are the most polished from all current junior pairs. Saying that, of course they are polished, they have been competing internationally for four season (this season is their fifth). So one could say, their progress have been much slower than the progress of some other pairs (who already moved to seniors), but at the same time, it is a pity to throw it away when they have the chance to be on top this season and move to seniors next season. I have no idea what their problem is with each other, what lead them to question whether they should skate together or not, but if there is something between them that doesn’t allow them to work effectively and makes it unpleasant experience to skate together, maybe it would be for the best to split up. But it would be a pity!
Re: Artemeva/Nazarychev, I wouldn’t worry about the throw yet. Don’t forget how little time all these pairs had this off season, thanks to Covid-19. Most pairs made mistakes on side-by-side jumps or had some issues on throws (e.g. touching the ice to stabilise herself, or landing on both feet).
