Code review comment for lp:~elopio/autopilot/fix1257055-slow_drag

What exactly is 'rate' measured in anyway?

It's the number of pixels you advance per iteration. This is really confusing for me, I spent a couple of hours deciphering the algorithm; but unfortunately, that's what you chose for Mouse API. I would prefer something like the number of seconds that the drag will take, but at this point we can't change the Mouse API and the best we can do is to make the Touch API similar.
