I have been helping out at a private club and trying to get targets set correctly. I know all the ATA stuff, but am looking for foot to % chart. The club terrain will not allow for a stake/T-Bar and have been using @ 21% off the table of a Pat-Trap and a small hand held radar gun. I searched on here and didn't see any threads for this and Geometry wasn't my strong suit in school, to convert from 9.5ft at 30ft, to degrees. Any help will be appreciated!
