6a80832140 Moves timing of interrupt sampling into prefetch queue advancement. 
As per comment, that is definitely the only place it can occur; I don't know whether it always occurs there.

260843e5b1 Starts poking at a pure total-based formula. 
On the assumption that any relevant DC offset will fall out in the wash. This causes one 400kb disk to boot in a Macintosh 128kb, another couple to do reasonably well. So it's better than what was here before.

e3f22e5787 This should actually be PWM, I think. 
I'm just unsure of exactly the proper formula, owing to my ignorance on basic electrical engineering. Research ahoy!
