Your explanation is more or less what I was thinking it might be, except one thing doesn't work out - I'm still a lot better at FFR than I am at other computer sims that are more like DDR than FFR is, and I've just been playing those with my keyboard too, because I don't have a pad or anything.

Ah well. Maybe it's one of those unanswerable questions, like how many licks it takes to get to the center of a Tootsie pop, or when CLAMP will finally write more X ^^
