Bummer that DJI disagrees Meta. Take it up with them please.
I'm glad to hear that DJI helped you out here. I assume that they analyzed the same flight record that you posted since the aircraft remained lost and I've no idea how much effort they put into that or what, exactly, they told you but, as several of us pointed out, the flight record was not ambiguous. For example, if you look at the last 65 seconds of your flight record as the aircraft continued to move further away, and consider the aircraft heading, flight mode, pitch, and speed, the problem is very apparent:
During the two phases of GO HOME (RTH) the aircraft is pointing to the west (250° true), pitched forwards at 25°, and moving backwards (away from you) at 10 - 13 mph. A forward pitch of 25° is the most it will give you in RTH mode, and would equate to around 20 mph airspeed. But it's still going backwards at 13 mph, meaning that it was fighting a headwind out of the west of over 30 mph. That's not inconsistent with the AirData analysis that I posted earlier, and the aircraft FC itself gave you 6 high wind warnings during the flight. Perhaps you have a different explantion for those data?
To forestall the obvious question about the sport mode interval in the data above, when it re-entered sport mode at 863 seconds, you applied full forward elevator for 2.4 seconds, increasing the forward pitch to nearly 35° and slowing its drift away from you to under 10 mph, but then (presumably out of confusion) applied full backwards elevator for 4.2 seconds, briefly boosting its speed away from you to around 35 mph. Then you centered the sticks and its speed came back down before going back into RTH at 884 seconds following a brief disconnect.
So, you can gloat all you like that you think @Meta4 was wrong in his assessment, but he was not, at least based on the data that you provided.
