You can very easily move several feet in one second. If the proximity

Are you really making those types of rapid movements around your TS?

Not intentionaly.

Several feet in a sec? *Are you practicing your TaeKwondo or are you
ripping a board? * When do you ever move several feet per sec at the
TS? *Around most TS accidents a gradual "push" into the blade?

The more likely cause of someone contacting the blade would be a slip or
kickback. This stuff *happens fast, to fast for a one second delay to be of
any use. In the case of brain fade, it might do some good.

If that's the speed that most TS accidents occur than we should give
sawstop grief for pushing that hotdog so slow into the blade in their
demos. *I would like to see the effect of the hotdog being pushed
"several feet/sec" into the blade.
Do you think it would still only make a small nick in the dog?

Actually, it would make surprisingly little difference in the size of
the nick although there could be some. There is only so much work you
can do in 5ms. IOW, there is no residual 'wind-down' during which time
any further cutting can take place. When that blade is gone out of the
path, it is gone. The cutting path recedes backwards and downwards at
that speed, you'd have to catch the blade on the way down. SawStop's
effectiveness isn't so much in the stopping of the blade as it is in
the disappearing act.
