Don't under estimate the float

[clydeaker]

One of Peach's greatest tools is her ability to float. I always took it for granted until I saw this you tube video:

I know it's not Smash 4, but it demonstrates the capabilities of a zero gravity float.
Notice how infinities are possible because jigglypuff has an infinite float.

Peach's air speed combining with her aerials knockback and hitstun make this obviously impossible for a smash 4 peach
