What I have observed is that the 'average joe' will not improve long term at least unless there is one critical factor. The willingness and ability to adhere to the instruction given.

No matter how good the instructor is, if the student doesn't commit, success is not to be. Kind of making a golf stroke, you need to commit to it else all who knows, it might work, it probably won't.

A sidenote, the short game fix is a bandaide in most cases. Cause if you have poor basics with the short game, you can get some good results, but it won't hold up and it certainly isn't going to help the rest of your game. I have seen more flippers get away with it in the short game only to see the same moves in the rest of the game that kills them.
