Window Motor question

I don't have too much experience running these window motors to know under what loads the PTC likes to trip.

I don't understand how this works, but a 20% increase in efficiency, what does that gain us in terms of performance? Say now we can raise it twice, and it fails half way up the third time. Would this give us a real boost in a match? Would it complete a third trip up? Four?
