it is just a consequence from the law of thermodynamics - more speed means more energy, more energy from the limited source means less time.I didn't know any of that. This is really useful information. Thanks for posting this!
where it gets hairy is - more speed may not mean more distance - when we go against the wind, and, together with less time - it all fails.
plus, the stock computation for RTH is built based on the windless - i think - situation based on the anticipated rate of battery consumption - what did they put into that algorithm no one knows for sure as code is not open - but - as many had a chance to see - it is pretty far from perfect.
it is easy to start dealing with it, with time, but, as i stated many times before - the best approach is to know where wind blows and do not go too far downwind as getting back may get tricky if wind gets stronger. or, make sure you have a lot of battery left.
also, an important thing to remember - old lipos deplete not like new ones, they sag and loose voltage way faster. dji code is not aware of how old your lipo is - it is done from the perspective of the brand new lipo. so, the power reserve it shows may not be the one you actually have.
