Daryl,
That day may be here sooner than you might think.
A friend of mine,GSEM, told me a story. He was visiting the show at Orlando last january. he went to the range to see some action. He stopped at one of the biggest brands since they had a Trackman and they where offering a "try out" to anyone who wanted.
He told me that they did fix peoples ball flights within 15-20 minutes and that without any "technical" advice given. Amazed by that, he did have a chat with the boys running the TM. None of them was instructors but they did know HOW to read the numbers and WHAT was needed to change for better ball flights. It did not matter which ball flight that was requested by the student, they did "deliver".
With the knowledge that you and many others here have, I hope that you get a chance to spend a couple of hours on a machine. I would also say that having a person who actually knows how to read the numbers is an imperative!
That IS teaching. I've been teaching that way for 20 years. Quality instruction should always be based on "improving" the ball flight and requires a good working knowledge of the impact collision conditions that create ball flight. Heck, I can tell you what your Plane, Path, Clubface, Angle of Attack, and impact point is, within a few degrees, WITHOUT a TrackMan. For example, I can tell you that your Path is too far left and your clubface is too open to that Path. But that doesn't mean you'll have any idea how to change that. I could simply say aim more right and close the clubface more at set-up. And if that works, fine. But a great teacher will more quickly and effectively guide you to produce the desired impact collision conditions, with a plethora of proven techniques, than you could ever do on your own.
A little precise info sometimes makes a big difference
This summer I explained to a couple of kids how side spin is created. They were attending a summer golf schoole and had no previous experience with the game. One of the kids had good moves but he sliced the ball big time.
I spent about 60 seconds, explaining the basic impact geometry to him, and how a slice sidespin was created and how he needed to impact the ball to produce a draw. I compared with soccer.
He said that he understood, and proceded to ..... <drumroll> .... hit nice draws straight down the fairway.
I don't know who were most amazed - he or me - but that was pretty awsome.
