using a ruler and calculater is cheating ..................... gimme a break
have caddied in 3 lpga tournements and you should see the stuff the pros use book with yardage and should see the notes they use I thought I was agood local club caddy and boy was I humbled by what the pros do
using a calculator to figure out quickly if it should be 60 65 or 70 % power on a shot smart
using the ruler or paper taped to bottom of moniter to indicate %'s on powerbar also smart
personally i would love to know what other calculations or formulas Charlemagne uses,
unlike others i want to get better not *** at my betters try to reach them anyway possible
so play practice and do whatever you have to do to get better and if you not willing to do that just SHADDUP and go play tigers game
