All this cutting edge technology and science is really shinning a new light on the golf physics.
To date, I haven’t read anything that has counter a long standing fundamental in the golf swing for normal shots; the club head should contact the golf ball before the big ball. In addition the contact point on the club face in relation to its orientation and path define the golf ball’s flight.
Technology such as Trackman offers a lot of what I would classify as raw data. In my limited experience and educated opinion I don’t see significant value of this technology for the average golfer in of itself, by itself. I do recognize that this can be an extremely power tool in the hands of an experienced and educated golf instructor. Removing bias and perception, translating the raw data back to the golf club, the golfer’s motion, the golfer provides the golf instructors the capabilities for ACCUATE high quality instruction.
The science today in golf offers explanations for what was guessed, corrects misunderstanding and offers a gateway into a new level of golf instruction. IMO: The bulk of the physics appears to be more related to the club head, club face and the ball. The science as related to the body’s role and more important the body’s capability in golf seems to be less researched or maybe less validate to science of the club head, club face and ball.
For me at least, I shall read and evaluate, but I will either need to seek out the professional with the knowledge and tools or wait till the technology and science can be packaged for a Do It Yourself who has limited resources.
For me I can not discern visually a 1 or 2 degree difference in my AoA, out to in, etc.; I must rely on ball flight and divots to evaluate what I guess you would I am perceiving my golf swing, golf club is doing. Monitoring my body is about the only way I can tell what my body sequence and balance is doing. Basically I rely on common golf wisdom which I am constantly re-evaluating, keep it simple.
I anxiously await the technology and science to convert into common golf wisdom for the masses, granted it may not be a path to scratch golf, but breaking 80 floats my boat. (HINT HINT Brian!!!)
My position has evolved over the years, many have tried on their own, claimed success, yet at the end I have seen few demonstrate long term success.
