Great question Steve. I just received my LabRadar last week, was looking at all the data and thinking the same thing.
I started out with Vortex's site which worked well for me and then bought a Kestrel with AB for a better WX source and the AB program. A few months later I found a deal on the Garmin 701 and have not used the Kestrel again. Love it. Using the truing page on the 701 gets me within .1 of a mil of elevation from 100 to 1200 yards so far. Have not had such luck with the wind, but I'm sure that's due to gusts and my inability to read the wind along the range accurately. Hope to try it out to 1400 this weekend.
Specific to your question, I don't know how to use all our new info with any of those devices. I'll be watching for an expert's reply.
Where are you in IL????
