How do you all feel about using sport mode to get somewhere and switching to regular to film and then back to sport to get back?

So, I designed a 5 mile long square shaped "course" and flew it once in Sport Mode and then again in P mode (OA off). Except for when I had to turn I had the throttle pegged in both cases. I then uploaded the logs to HeathyDrone and their algorithm predicted the Sport Mode mission would have had a full battery range of just over 7 miles and the P mode mission full battery range was estimated at 9 miles. I repeated this exercise twice with similar results. So, there is an efficiency penalty for using Sport Mode that will vary by how you use it but looks to be about 25% in my crude test given the conditions of that day and my calibrated throttle thumb.
From a more subjective standpoint, the noise level, at say 200', is noticeably greater in wide open Sport Mode than in wide open P mode if the MP is directly overhead. If that matters then P mode it.

For sure. But it is more complicated than that. For example, if you cruise at 10mph your range will be much less than in my "experiment" even though the drag less. Even if you assume a 24 minute air time at 10 mph your full battery range is only 4 miles...no where near either the full throttle P mode or full throttle Sport mode range. My experiment is only quasi scientific at best. Just trying to find a general "mode" that will maximize distance flown as opposed to time aloft.This is because drag (air friction) goes up by the square of the speed. If you double the speed the drag goes up by four times.

I have heard the same 15 mph figure quoted as being the most efficient too. However, the math just doesn't work...which is why I performed my little experiment. Even if you assume the most optimistic flight time of 27 minutes (which is very very generous) at 15 mph you only cover 6.75 miles. And this ignores ascents, descents, turns, etc.. Many people have demonstrated flight distances greater than that including my own experiment. In fact, the stated signal range by DJI is 4.3 miles implying at least an 8.6 mile distance capability...clearly requiring more than 15 mph headway. 15 mph can't be the most efficient speed. It must be something greater.Yes of course. You can hover it and the parasite drag will be zero but your flight times will be short and your distance will be zero. There will obviously be a sweet spot where efficiency is maximized. I think with the Mavic it has been determined to be around 15mph.
Signal range doesn't imply anything, it's really stating the capabilities of the RF system on its own regardless of whether you can actually use it or not.IIn fact, the stated signal range by DJI is 4.3 miles implying at least an 8.6 mile distance capability...
