At THE point that the target line would emerge at the BACK of the ball - Dead centre. All putts are straight putts as far as the stroke goes, mother earth takes care of the rest.:)

The bullet hole direction would need to match impact fix and the considered variables (hinge action, etc), no? Wouldnt it need to compensate (directionally) for the amount of time the ball is on the clubface?

Personally, I prefer a shoulder stroke - better now as pivot controlled hands - uh oh...am I in trouble now??? :)

Philly,
You can't have pivot controlled hands in putting because your pivot is zeroed out. I have seen you putt, remember the shoulders are double agents, part pivot, part power package!!!


Todd

Interesting point.

Even if you zero out the Pivot, if you maintain Lag Pressure (which you should have even in putting!) relative to the Body rather than the Plane Line, that will be symptomatic of a Pivot Controlled Hands procedure.

The Arc of Compression?
 

Hey Tongz
If the club is against the ball on an arc, isn't it theoretically possible that the bullet-hole should also be
an arc? STAOC..hmmm.
Bill:)

Wildbillmckinney,

"This third direction is the direction of the compressing force. The momentum of the violent return flow after impact also distorts the ball by exceeding the the normal dimension of the compressed point." Compressed Point here. Page 13 TGM.

So the bullet hole throught the baseball deals with force vectors. Page 17 2-c-1 #2B. Take this picture and turn it upside down. Now take a pencil and draw from compression point on the first ball to the next. There lies the angle of approach. You can also visualize the "curved blur" of the arc of approach. You can also see the LINE OF COMpression.

By the way- that tour player that was mixing arm only and shoulder only stroke---He was Danny Ellis. So THE Golfing Machine is definitely making a impact on tour.

Interesting response.
My thinking has the point of impact still slightly inside aft quarter...even when putting. Video shows this produces an end over end roll. Trying to stroke through the back center of the ball creates a slight cut stroke spin. This is because we stand astride the ball, not behind it.
Video was done in 2001, and not uploadable. It would be interesting to hear a more sophisticated analysis of this question.

I have to think the same way.....I'm not sure how much towards the inside though.....prolly pretty small.....but there anyway...

....what do you guys think.

the line of compression bends? moves?

good lord....

VJ, would you mind explaining what he was doing in a little more detail. Also, I assume all of these strokes are what they are named; wrist is all wrist, arm all arm, shoulder all shoulder. correct?
