I'm new to csvview too. I'm very impressed by it. It opens the door to a lot of performance data that we would otherwise not be able to see. I'm just a regular flyer, taking pictures and trying to not lose the drone. However, as you are trying to do extreme long range missions I think it would be worth investing a lot of time into cssview to review the missions youve done in the past and figure out how to push the envelope out to where you want to get to. Else its just trial and error/(lost drone).
