Best Speed to acquire max distance? Best Speed to acquire max time?

[CoolBreeze]

Understand many variables, nevertheless...
Anyone know of a controled speed/distance and or battery flight time experiment?
I have read sport mode - aprox. 40 mph, RTH mode - aprox. 20 mph and now 32 mph as best way to fly. dji Mavic states 27 min. flight time at 17 mph.

I'm trying to gauge this number, too. My guess is to mimic the RTH speed of around 22 mph.
