Mizjoe - I've been carrying on a conversation about this on the TGM website. For hitters the 1st accumulator can still be generating thrust DURING impact. For swingers there is #3 and possibly #4 that can still be generating thrust. Remember that release is usually not fully complete until AFTER seperation. There is also a difference between a glancing blow and sustaining compression.

Good stuff Ringer, but the answer is Lynn Blake's post earlier in the thread.

But, I do agree that the THOUGHT must be accelerate to the Follow-Through!

Ringer,

The intent of more speed at separation will not give the reality of it. Ball compression will drop impact speed a minimum of 20%. But you want that intent, or else you'll get even more of a speed reduction.

I've heard Miller claim that he was measured as being "the only guy who's speed was faster after impact than before"

anyone know if/where there is data to back that up? Seems that the 'official' answer is that this isn't possible.

It isn't possible. "The Search for the Perfect Swing" by Corcoran and Stobbs does a nice disertation on the subject. It even includes pictures for the verbally challenged.:D

Yes, I know Mr. Kelley didn't agree with everything they wrote.;)

There is a guy who's known as the "decelerator". He has reportedly jumped out of an airplane and survived the fall and more than once. He claims to have figured out a way to reduce his speed before impact without a chute. Johnny Miller, on the other hand, is the "accelerator" of the golf world.

uh, what? Mizuno Joe, did I read that properly?

A guy who jumped out of airplane more than once and survived the fall? I've got to hear more about this.

I knew a guy who jumped off the Mississippi river bridge and lived. They found him clinging to a buoy with a few cracked ribs. Totally amazing if you are familiar with the river current in N.O.

Where is the clubheads greatest speed in swinging and also in hitting.

Maximum Clubhead Speed is achieved almost instantly at Release for both Swingers and Hitters (2-M-1 and 6-F-0). The Clubhead does not pick up Speed during the Release Interval (the Overtaking of the Hands by the Club). Instead, it tends to slow down!

Swingers use the Body Pivot as a Rotor to accelerate the Left Arm. This generates Momentum Transfer (from the Rotating Body into the extending Radius of the Left Arm and Club per 2-K) and the Throw-Out Action of Centrifugal Force. This combination virtually eliminates Clubhead Deceleration during Release, and as a result, the Clubhead maintains a constant speed into Impact.

Hitters, on the other hand, use the Body as a Launching Pad from which to Drive the Right Arm. Hence, Momentum Transfer is unavailable to prevent Release Deceleration. Therefore, the Timing and Trigger Delay of the Right Arm Thrust become critical in preventing a massive slowdown of the Clubhead during Release. Learning to handle this Release Deceleration problem is one of the biggest stumbling blocks the Swinger must overcome when learning to Hit.

For both Swingers and Hitters, Impact is a violent collision of Ball and Club. Since the Ball hits the Club as hard as the Club hits the Ball, the Clubhead decelerates significantly. The Ball's mass is about one-fifth (20 percent) of that of the Clubhead, and so the Clubhead's Approach Speed is slowed to approximately 80 percent at Separation. It is important that this Impact Deceleration be minimized because in addition to its own 70 percent Coefficient of Restitution, the Ball picks up 100 percent of the Clubhead's Speed at Separation. In this department, the only defense is the familiar mantra of The Golfing Machine...

Sustain the Lag!

This is what Homer Kelley said also. I like my chances with them.

Matt,

Yes, this "story" was on some cable channel several years ago. The 1st time the guy's chute didn't open, and he survived. The next time, he supposedly packed a chute, but didn't open it. While I know of several instances of jumpers surviving when their chute didn't open, I don't buy this story, because he claims he not only survives, but lands on his feet by mentally emitting some sort of field around himself. People who survive this have to roll and land exactly right, and on something relatively soft. I think this guy decelerates about as likely as Miller accelerates after separation.
