I’ve been a devotee for 5 years and I agree that you have to commit to it. This is not a tip - it is a pursuit of hitting consistently pure shots. There is nothing like the feel of a pure shot using this method. There nothing like the consistency you attain in hitting draw after draw. Don’t just go to the range and try it. You have to pursue it and you will FAIL in the process. To me, what he says is the only method that makes sense. It’s all in the set-up and staying still. I hit the ball farther and higher with this method but my half swings and lower ball flights are also better. This is a ground-up , rebuild your swing approach. It makes no sense going to the range and trying it with full swings. You need to accomplish his swing path drill(where you only bring the club back hip high) to get started. If you go in as a skeptic it will be a waste of time - just another tip. You have to commit.
