Dang, what a long thread on this subject, lol.
Pikas CG goes from 19% onwards. It might be a little earlier then 19% though. Around 50%ish pika cant start the CG anymore, but I dont think falco can ever footstool out unless the CG is started too early. And the later its started the less damage it does.
Also the cg technically start at 0%. I cant remember if it was ever tested, but pikachu has a boost pivot grab as well. Ive used it on DDD before to CG but havent really learned to do it well or to test if it works on falco.
Also while its certainly a feat to beat pikpiks, I think its generally regarded that hes not good at the Falco MU and cant cg properly. Hes said so himself.
I think falco can do OK in this MU, but that might mostly be because pikachu players dont really bother to learn much about the MU anymore. It might be awhile to see how well falco really can do in this MU when both players of about equal skill know the MU well. I've played larry quite a few times so I think Im learning the MU pretty well, but he's much better then me overall
. However given equal skill and knowledge in the MU, I think that Falco should not be winning too much.
Last note, I think flat stages like FD are better for camping then trying to platform camp. SV might be better then FD though.
