I'd like to see the engineering figures on just what that extra 114
milliseconds of time means in the travel of the blade.

Easy enough to calculate. Assume rotational speed of 3600 rpm = 60 revolutions
per second. 114 ms * 60 revolutions = 6.84 complete revolutions of the blade.
If it's a 40-tooth blade, that means 274 teeth. That's a lot of cutting.
That's a lot of ouch, and a lot of damage, if the object being cut is your
finger.

SawStop reacts in, what? 3 ms?
