Low battery RTH Sports Vs Normal

[Heidelburger]

After watching some Touch & Go Return to Home with low battery vids, I got to wondering if anyone has done a definitive test on the Best Option. Flicking to sports mode will give you more speed and take less time but use more power OR Normal flight will take longer but use less power. Which gear should you chose or should you flip a coin?
Just seen a couple of old threads on this and it looks like opinion is split so any fresh thoughts would be great

Depends on if you're flying against the wind.

Naturally you couldn't fight a 20mph wind in normal flight but make slow headway in sports .. I agree But take the wind out of the equation What's the most efficient battery /time/distance flying mode?

My own flying has demonstrated that I cover more distance per battery percentage point in P mode versus sport mode. It just feels so much longer, because it's much slower.
