I vaguely remember someone trying to make the effective delta applied vary based on the gesture distance/velocity or some such a while back. (And I very well may be remembering that wrong).
That said, I'm a bit puzzled, as the minima for that gesture is and has always been zero. i.e., you can actually turn it off that way.
That definitely works on the H2O that I have right next to me right now, I'll get back to you later about the Forma
