Peeps, The program is written for Windows based programs. If you are "windows based" just download the program and run it. If you are using a Mac, you've got to do some fudging to make it work in 'Mac Numbers'. It will work in "numbers", but you've got to do some 'translation'. Here is the Windows link: https://sites.google.com/site/bilkosputterpal/jacobsgolfstats/wind-calculator-program
It WORKS, but you have to be aware that as WGT changes it's play parameters or you mess around with 10 different balls, you have to apply corrections to Bilko's results.
You look like you're doing pretty well without it !!??
Good Luck.
