Reason being is for some freak reason it can happen to damage the motor...or not...who knows...IMO skip the damned a little knock is ok. NO KNOCK IS GOOD. Period. I don't care if you have a half of a degree, or two tenths of a degree...its a half degree or two tenths too much and is still taking power from you, even if it is a hair on your ass sized amount. I'd rather be safe than sorry...and trust me man, I've been through enough motors to find out.
