I think this is a recipe for disaster. Where do you draw the line? What defines a divot, the slightest imperfection on the ground, or a 3 inch crater? On fairways only? What about a divot in the rough? What if you are standing in a divot? I think this whole thing is open to interpretation and would slow the game down, cause cheating etc.
Another example is the mud ball. I agree that this is unfair, but what defines a mud ball? Some slight grass mark on your ball, actual mud caked on it? To me this is a way of improving your lie and again is open to interpretation.
One of the beauties of this game is the fact that some of it is left to luck and "rub of the green". You should play the ball as it lies, just like in life. I was plugged in the rough on Saturday, within 20 ft of the flag. Impossible shot, so I had to take a penalty drop. Should I have got a drop as my stance possibly could have been in a divot? Or because theoretically I could have had a mud ball?
Just my 2c.
