you can wiggle out and jump near 100% cort with fox, and chain grabbing falco isnt really feasible, i usually go for u throw to dash attack at those percents, into w/e else i can muster (I.E. uair to nair, or full jump fair)
CF can escape at like 70% too.
as for the FC's...
really nice, very fast. I generally FC slower but thats because I generally move forward with my nairs so I have the extra time from doing a couple frames of dashing. I actually have some trouble doing nairs in place but It doesnt bother me because well moving with nairs is more useful. But thats still some nice speed you got going. I'm almost a little jealous =)
As for the match itself, it seems you put a little too much emphasis into FC'ing in place. You can tell that you just significantly slow down during an actual match, and then you make some really poor decisions, like wavedashing out of sheild instead of sheild grabbing that fox when he f smashed you. And then some random FC aerials that didnt make much sense at all >_>. There were plenty of times where you gave up some reliable kills for something stupid flashy, and may I emphasize that that is the quickest way to get trapped in a level of mediocrity. But I wouldnt worry cause your peach seems good and you just need a little bit more practice with some peach things so you dont give up easy combos and kills.
