Free wind calculator I made (this works best with level 81 Nike ball)
Your tailwind formula is 100% on the money. It seems to be using 38% which is perfect. However, your headwind, at least the way I have everything mapped is substantially short. You seem to be using 57% head (63-65% works perfectly for me). Any chance you can provide some sort of user interface where we can manually change the Wind Formula?
Also, it would be a nice addition to have something that told you how many feet/or yards to aim left or right. I currently use KATS and if I were to switch to a new program that would be a must (to save additional time doing the calculations myself).
But to end with, it seems to be working perfectly and is a great addition to someones WGT tool portfolio.
