I am not debating the fact that a snap release can have more speed than a sweep release, I am only addressing your statement that after release it starts slowing
from 2-m-1 basic power
...Centrifugal acceleration is staunchly proportional to the angular speed of its center and reaches a maximum speed almost instantly after release and tries to remain constant...
Like the clubhead, I've tried a lot of things that didn't quite make it!
