It does not appear that the technical panel downgraded any of her jumps at Nats. IMO, Kimmie still has a LOT of work to do on all things other than jumps to get the difficulty levels up, and also the execution up. I agree with Doris that she was more "juniorish" than I expected. But she's still young and there is no reason to think she can't or won't improve these areas in the future.
I did not notice Kimmie attempting any 3A's in either practices or warmups. Did anyone else? There's always a lot going on and it's easy to miss things. Of course that doesn't mean she's not working on it at home, or won't be working on it for Oly's and World's. I have no idea if this was the strategy, but it would make sense given the circumstances at Nats to focus on nailing the 3/3's and not risk the 3A in order to make the teams.
As noted by others, Emily certainly has her jump issues to work on. Her non-jump element levels are higher than Kimmie's, and she is certainly another "bright hope" for the next 4 years. I think Katy Taylor is another important one to watch for the future. I was also impressed with BeBe - I wonder what her future will hold? Is there any hope for Alissa to fix her jump issues? In terms of a gorgeous skater to watch...I think she is the best of the young bunch if she could fix that. But it will never happen for her if she can't find some consistency.
As far as Kimmie's medal chances at World's...It's hard to tell without knowing for sure who will / won't be there. IMO she is nowhere close to beating the current top 6 or 8 or maybe even 10 in the world unless she skates "perfect" for her (right now) and there are mistakes by others. Right now anyway, Kimmie's only weapon is 3/3's, and if she makes mistakes there, she's not got much else to fall back on to "make up" for any jump errors. That said though, I think she jumps a lot like a cat - she manages to land on her feet (well, foot

) most of the time. And that will serve her very well as she works to improve the other stuff.
