you are better off
I had a 30 year old bad habit to brake. Didn't know i had till ready found it.I had a one on one 8 hour session with Randy almost exactly a year ago. I was literally a beginner at that time (still am). The video of your stroke is truly revealing and educational. I have taken lessons since then from people (professional player(s))who tried to change what Randy had taught. I choose to subscribe to the Randy G school of thought.
I'd love the opportunity to get to go again.
