n/m got the answer
I was trying to hit the ball with my hands instead of swinging the club.
Dear jenhaoyen,
As you probably have read in some of my previous posts, I believe from a basis of science AND golf APPLIED science, that TEMPO and DYNAMIC BALANCE are the 'prerequisites' and crucial aspects of the golf swing, and there must be consistency for the tempo, and stability margin for dynamic balance. I have also stated that IMO, ALL swing errors can be found to have a breakdown in one of the above (THE CAUSE), and therefore the error you see is THE EFFECT AND COMPENSATIONS for the breakdown in either tempo or dynamic stability.
I am sure I will be challenged on such a bold assessment, but I am comforted by being able to stand on the shoulders of Dr. Robert Grober, and Sr. and Jr. John Novosell for their contributions to my understanding and application of their science to the above.
So, concluding that I have a strong respect for the importance, in the context of your post, of TEMPO, here is what I suggest for you.
Let your body become the source of power for back and forth HORIZONTAL swings with a driver, similar to a metronome, and over 10 swings, increase your 'power level' from 50-100% of your normal swing. Pay particular attention to your dynamic balance (a free by-product of this TEMPO exercise), and while trying to maintain a rotary-dominant pattern, NOTE THE TEMPO AND RHYTHM OF YOUR UNIQUE DYNAMIC BODY/GOLF CLUB SYSTEM.
Now, starting horizontally, and selecting the power level you intend to play with, over another 10 swings or so, gradually lower the swing plane to that of your standard driver conditions, hopefully striking a rubber tee for feed back as to the timing AND SOUND of impact. During this series of tests NOW MENTALLY RECORD THE TEMPO AND RHYTHM CHARACTERISTICS of what will now be YOUR STANDARD SWING.
It is currently my hypothesis, with a whole lot of informal testing for support, that when you DEVIATE from these now PERSONALLY DERIVED characteristics, you will begin to accumulate swing and resultant golf ball trajectory ERRORS you do not want. The FIX is soooo easy, even on the golf course, and even under the highest degree of competition, just, at full power, repeat the exercise noted above for 3-5 swings REESTABLISHING your standard TEMPO AND RHYTHM, and in less than 15 seconds, launch (sorry, a carryover from my rocket scientist days) the golf ball with confidence you have replicated the CRUCIAL characteristics that control the quality of your shots.
Naturally, it would be improper and incomplete if I did not suggest/require that you have addressed, practiced and committed to "Bumpy back, keep it back" to provide the CRUCIAL additional piece of lower body DYNAMIC BALANCE AND STABILITY MARGIN to provide the best chance of another perfect shot.
Please try this, as I , in my passionate pursuit of 'golf truth' NEED much more independent testing and support to accomplish what I am attempting, that is to provide both the golf professional instruction and playing communities the BEST, science based INTEGRATED solutions for the crucial elements of the golf set-up and swing.
Thanks for your interest, and please post your experience with this approach,
Respectfully,
