Yes Arc that helps a ton, I had no idea the hitbox gets smaller, I always just thought I was floating too high/far out and that Foxes were hitting my feet or something. I also try to do the Armada bair edgeguard, and if you notice he'll always pull a turnip right after the first bair, so that after the second bair he can follow them off-stage and gimp with the turnip when they try to come back for a third time...he's so good...
I know there's a lot of other good Peaches out there, but I think I'm going to keep on watching Armada exclusively, since I've found that sometimes watching too many different playstyles can be counter-productive. Armada is just so efficient and in control, which is the complete opposite of the player who I modeled myself after (PinkShinobi), but I find that the more of Armada I implement into my playstyle, the harder I am for opponents to deal with it seems. Now if I can just substitute some of my nair spamming with well-spaced fairs I think it'd put me that much closer
EDIT: Raith you should let us know for sure by 4:30 or so
