Kudos to Alissa for upping her difficulty, but I wouldn't necessarily dismiss the others as mediocre and unwilling to put in the work to improve. If the 3-3 isn't consistent enough then, frankly, it isn't a good idea to put it in a program. Rachel had them before but obviously age and injuries have taken their toll. Ashley had problems with downgrades, and often Mirai has problems with downgrades in the FIRST jump of her 3-3s.
In a way I feel like the current generation of senior skaters got screwed. They grew up not learning figures and not learning proper jump technique. It was all about 7 triple, aesthetically-pleasing programs. Now you can't even get to 7 triples without a 3-3, edge work is scrutinized, and points taken away for clean but technically improper triples. Certainly the ISU was correct to address these problems and change the direction of scoring. However, I feel bad for these skaters who learned how to become a champion with skills that now seem almost antiquated.
