The TPI researchers show you what most Golfers do. They are measuring Speed, not Acceleration Forces. They don't show you what most golfers should be doing. That's a problem with these researchers. They don't know about the possibilities and the Options. They take measurements and tell you what they are. Those kind of people will tell you to swing harder. They will tell you to over-accelerate and they don't even realize that over-acceleration is the problem. The researchers who supported "The Search for the Perfect Swing" didn't know either. Homer Kelley knew.

TPI are like the 'washing machine repairman'. Ask them why it doesn't work, and they reply 'because it's broke'.

Jeff, forget about the cameras and pictures for a minute. The Hips are leading and powering the Right Shoulder which pushes the Left Shoulder which pulls the left arm. Pivot Train.

The initial Blast off the chest of #4 happens because of Right Shoulder Thrust became less than the Velocity it produced. Over acceleration will blast the arm away from the chest too soon every time. Homer Kelley said "Instant Hip Acceleration", he didn't say 'do it so fast that your left arm blasts off of your chest pre-maturely'.

Thrust is the "Rate of the Acceleration" not the "Acceleration" (which is the rate of Velocity). SO, the Thrust moving the Left Shoulder dictates the Rate that the Left Arm will accelerate and requires only that the Pivot train keep moving, even without accelerating itself. The hips pull the Shoulders through the Impact Interval and beyond at a steady speed to provide an increase in Mass. The Left Arm may have started at Zero MPH at the Top of the Swing and reached its maximum speed in MPH at or just after impact, but it is still an Accelerating Force that doesn't diminish until the Hips Stop Pulling and Leading the Shoulders.

The Clubhead should reach its maximum speed three feet after impact, or at least that’s what you should be trying to do. That's the #4 Accumulator. If you don't have that, then you're just simply going around in a circle. It's not how fast you move your Hips...it's How Far you Move Them.

Do the TPI Models look like this guy? Your TPI model is using a Hand Throw from the End of the Backstroke (A very Questionable procedure) . Even the Model has 'stopped the Pivot' to avoid a pulled shot. And he's just a simulation. Geez. My guy uses a Shoulder Throw followed by a Wrist Throw.




Additionally, Consider this. When a baseball Pitcher throws a pitch,,,,,the ball keeps accelerating because the pitchers rate of acceleration (Mass) at release was increasing. The Ball is slowest MPH when it leaves the Pitchers hand and fastest in MPH when it crosses the plate. Hmm? I wonder what the TPI researchers would say to that?? I bet that they would tell him to 'Back up a Bit'.
