i pulled back on it slowly on it had only 2 movements so each one i guess
would be 12 1/2 ft thanks 4 your help :))
No. It isn't exact. Watch the distance between each move. Basically you have 3 spaces, 2 of them the same and the third something less. That makes the first 2 moves less than 12 1/2.
The best thing to do to learn this is head out to BPB front 9. Get on the green and putt back and forth, watching what the different moves on each scale give you. On in 2 or 3 gets you 7-8 putts. The second and third holes have good, long, flat greens that are good for practicing.
