Richard4168:There's no set number that would indicate a determined distance per dot, but you could figure 3 to 6 yards per dot as a general estimation
This could be a little high, Nikes with 4,5 dots add about 5-6%, so the actual distance dependes on the club you're using. So, a 60y wedge will go for 63, a 115y PW will do around 121, a 160y 7i will go around 168.
I'd say about 1-1,5 % difference per dot.
