indeed...

For a finger saver an emergency stop mechanism would have to stop the blade
in a few teeth passings. ...

SawStop is a few (10's of iirc) msec.

By several "tooth passings" a finger is already pretty well history...

Sawstop stops the blade in 1/200 of a second, according to their Web
site. At 3450 RPM that means the blade stops in .29 revolution, which
with a 60 tooth blade means that 17 teeth have had a shot at your
finger.


That may be true, but they still don't do any harm.
