Well about how to conduct… first get CapFrameX (it’s free). Then fly and save a replay (1,5/2 mins will suffice), for example with SkyDolly. Then repeat this replay using always the same meteo/time of the day, and adapt the various options as you want to test the various things.
If you have time, repeat 5 times each test and aggregate, keeping the medium three. Otherwise, just go with 1-time testing.
About interpreting the results, it’s pretty self-explanatory in CapFrameX, there are plenty of hints.
