I’m assuming the survey is for one golf lesson (about 1 hour) and not a series of lessons (which would have a different success parameters) …
taking the golfer, with their unique swing, “moving the numbers” utilizing techniques (as explained in the trackman video, where I had my epiphany) thereby getting the d-plane closer to tour average as achievable for said golfer (verified by a radar device) and giving the golfer a take home on what they need to do when they practice on their own
the golfer understanding why they are hitting it better, although valuable, is not necessary (more of a long term understanding of the building a swing and might not happen in only one lesson)
