A few frames on top of the platform/OS/hardware latency may begin to cross into the threshold of perceptions for initiation of continuous movement. If your hardware already has 30ms of latency, then a few additional frames makes approximately 70ms. What you actually see with your eyes when your program consumes 30ms at the start of a scroll may be much larger. However, you already have a few pixels (not time) of intentionally introduced slop in a scroll view. I'd like the ability to play with all of these constraints (including slop pixel amount), remaining frame time, acceptable latency for initiation of gestures, in order to reach what I consider to be a great user experience.
