Yes easy, calculated from the flight log 3970 m / 12 minutes x 20 minutes = 6600 meters, it's even better. This at 20km / h on average.
But the secret is a cool speed, no sudden acceleration, to plan to start against the wind and finish in the direction of the wind.
Adopt steady drive, cool flight, and time gain.
Do not use sudden acceleration that exhausts the batteries.
What is not possible in flight Survey but in flight video landscape.
