[QUOTE="Dave King, post: 21922, member: 3"] Well, isn't learning great!! I'm going to try that 1 mile shot again tomorrow and was puttering with the RBC to get an idea of what I'm up to. I was working on the GPS determination and adding elevation components to get an "auto slope" going. All of a sudden I get this sickening feeling that I'm screwed up. GPS is flat land position!!! There is no slope to take out... for about a quarter of a second I was pretty happy then it occured to me that NOW my WIND CORRECTION is going to be buggered up. Well, for GPS positions I need to add slope into the distance to get the proper Time Of Flight (TOF) and wind component. I feel like a need a sword to cut this ever growing problem (Gordian Knot) apart. Maybe I'll just break down and buy a program but then what would I do for mental diversion(s).
