I have one I made up pretty simple Let me know where to send it it is made with number for iOS system but can be converted to excel . It will only tell you how far to putt given green speed and elevation . Distance calculator will also tell you appx how far you need to hit a shot given distance elevation wind direction and type of lie to include adjustments for hitting off the tee. You need to know your clubs and ball on how far they carry . Just let me know how to get it to you I do not mind sharing and helping out if it works for you.
