Sorty but I don’t agree.
These are the Most likely score rules:-
“If the ball lies on the putting green, and is no more than 5 feet (1.5 metres) from the hole:
Add one additional stroke.
If the ball lies between 5 feet (1.5 metres) and 20 yards (20 metres) from the hole:
Add 2 or 3 additional strokes, depending on the position of the ball, the difficulty of the green and the ability of the player.
If the ball lies more than 20 yards (20 metres) from the hole:
Add 3 or 4 additional strokes, depending on the position of the ball, the difficulty of the green and the ability of the player.”
The bold bits surely show that there is judgement involved, you have to assess or judge how difficult the position of the ball is, how tricky the green is and the ability of the player.
There really is an option as to how many strokes to add and in both of these cases above the ball can certainly be on the green.
Oh and by the way unless your going to take a tape measure with you you’re also going to have to judge the distance from the ball to the hole.
