[Yoda]

I'm fascinated by TPI's designation of "rotators" and "thrusters". How did they come to make this distinction? What do you make of this Yoda? Thanks.
O.B.

PS Oh, how do the stats line up? How many rotators vs how many thrusters how many somewhere in between the two extremes? I got a feeling there a more thrusters out there than we would have thought a few years ago.

O.B.,

The descriptive designations of Rotator and Thruster came directly from TPI's Dr. Greg Rose and his interaction with a handpicked team of TGM instructors in a day-long meeting last year. He told us TPI had made the distinction based solely on personal observation of the respective motions.

When we explained the TGM concept of Hitter versus Swinger, there was a collective "Aha!" from their assembled group. Their research had picked up on the two decidedly different Shaft stresses in the Downstroke -- radial versus longitudinal, i.e., back of the Shaft versus top of the Shaft -- but they had no idea what was causing the phenomenon.

I don't have access to any definitive information as to their stats on this subject. It was all new to them, and they had not yet done anything with it. We were told they would do additional work reconciling their ideas with ours and get back to us, but so far . . . nothing. And we've not pushed it.
