Yes, playing with my trackpad, the two-finger scrolling works as if it's sending a up/down arrow key every centimetre or so I move. Maybe a two zoned approach will be enough for everyone, where it scrollls just one tick if you only move it up to half way, but sends repeated clicks if you move it all of the way, at perhaps some user definable frequency if no happy solution can be found between all the users with their pyras thus far (and willing to contribute to this thread).
