More dramatic improvement courtesy of Ted Fort.
 

When Ted Fort in part two of the Lynn Blake/Ted Fort/Jeff Hull video said that if he does a practice waggle, he choses to practice a short piston like zero pivot motion concentrating on hitting out from 7 to 1,I was quite surprised. Was it possible that a motion that looks fairly routine, was worthy of Ted's carefully focus, right before he began his swing? I resolved to practice this motion as precisely as possible and find out why Ted was occassionally using it as a pre swing waggle. I started going to the driving range with only my sand wedge. I hit either 100 or 200 balls at a time, rotatng between hitting basic motion zero pivot chips to a water drain out about 40 yards, and to hitting acquired motion pitches to a small green with the flag being about 75 yards away. My primary focus is the information supplied by Ted Fort about how the right arm should go back. (I frequently grasp my left wrist with my right hand (as he did in the video) and watch my right arm's precise form on its way back. Then I really try hard over and over to make sure that I am duplicating that form as precisely as possible. On the forward swing, I alternate focus either a piston like motion or a paddlewheel hit in which the right arm drives the flat left wrist forward, making sure I "hit out" from 7 to 1 to a two arms extended finish.

I am astonished at how much improvement has occured in the last week or two of focused practice. On both the 40 yard chip shot and the 75 yard pitch shot, I was close to being automatic today in consistently being two putts distance or less from whichever target I was aiming at. While the zero pivot basic motion is clearly 100 percent related to my concentration Ted Forts part time waggle, perhaps the slow crossline hip downswing waggle that I also learned from Ted is contributing to my new found accuracy with my acquired motion pitch. Thanks again Ted and Lynn!!

Any additional suggestions?

when Hitting...
 

In using the Angle of Approach procedure, you must SEE the clubhead move away and return on a visually straight line. The clubhead visually covers this line. Do not be as concerned with the clubshaft as it is of lesser importance than the covering of the line with the clubhead.

At times in using Basic Motion, I watch my hands. At times I watch the clubhead blur. They are both very helpful for different reasons.

I'm happy that the videos were helpful.

There is clearly tons of swing data that can be monitored by the golfer. But because there is a finite amount of focus available, a golfer must carefully chose which data to pay close attention to and which to pass over. It seems from your last post, that when both ones hands, and the clubhead, accurately cover straight delivery paths, as an added bonus. the shaft is likely to behave properly, without direct monitoring.

I am a huge believer in not learning a technique 70 or even 75% right, but rather to keep searching through the feedback to allow more and more efficient techniques to be developed. Thinking about it now, it appears that the shaft's plane is likely a by product of the hand and clubhead paths. So by alternatively monitoring the hands and the clubhead blur, it will be easier to locate the source of additional swing imperfections.

In my perpetual search for a repeating, accurate golf swing, you, Lynn and other members of this forum, perform the role of a compass. Time after time, when you point me in the direction of true north, my resulting improved performance, demonstrates that once again, you have me successfully moving in the right direction.
