I mean that many things in real world do not go to speed N from speed
0 without accelerating (speed 0 + a bit, then speed 0 + a bit
more...). For your foot case, it would be a special case (and maybe
foot should deform, to show the compression of the hit).

Well, from what I learnt, things that stop sharply are not good (see
why I say the thing about compression). Overshoot, anticipation, arcs
and such things are good (even exagerating for toons).


Different "schools" of animating, I guess. You seem to prefer defining
the max always by a key frame, and if any to points share same Y (by
pure luck or on purpose), it means the area in between has to be flat
always, while others define it using the curves as a whole (they can
get the flat transition, but not necesarily always).
