I thought the Averina sisters are rhythmic gymnasts, but perhaps the gymnastics are labeled differently in different countries? In US - beam, vault, floor, bars, etc. = artistic gymnastics; ball, hoop, clubs, etc. = rhythmic gymnastics (although I always thought the word "artistic" better describes rhythmic)
Getting back OT, I've never heard of any skaters complaining about music starts, timing, etc., and it is interesting to hear ic3rabbit's perspective since she has that experience.
After far as program starts are concerned, I've always been curious about pronounciation of skater's names, and if they submit anything in that regard so the announcers have some guidance when announcing them at the start (if not, I think announcers - and commentators for that matter - should do their homework).
