Many people cannot react to several frames, it is usually a predictive choice instead of a reaction. A great example of this is the Millie Blocker written in flash some time ago. It tests the reaction time of a move with a startup of several frames, and as it turns out is not so easy to react to without predicting. http://www.teyah.net/MilliaBlocker_v0.3.swf

Regardless of where we draw the line of reactability, with a sufficient number of rollback frames, a move that was on the reactable side will shift to the unreactable side.
