ed Sadly, with golf being what it is, poor (i.e. not knowing the correct BFLs etc.) instructors still manage to improve golfers. And more bizarrely, golfers still go back to the same poor instructors every week even when they are not improving! I have targeted many golfers at my local club that have been having lessons for years with the same old pro and steadily gotten worse, and they tell me, "I like Paco, I enjoy my lessons with Pedro, José a great guy!" Unbelievable.
