NO. How many bowlers who use a RAMP are able to MAINTAIN a high average and of COURSE there are always exceptions. IF the bowler uses NO arm muscle to let the ball drop from that overhead height, isnt it the SAME as using a ramp? The BIGGEST difficulty might be staying balanced at the release because holding the ball OVERHEAD and releasing the ball would require different positions unless he was doing a SLIDE step at the end.

TOO many IDIOTS, so LITTLE time.
