Wow.

1) You can see the leading edge of the elevator is up, indicating that the pilot is commanding forward stick. This is the recommended procedure for a conventional gear takeoff- raise the tail to lift the tailwheel, reduce angle of attack (and induced drag) and align the airplane with the direction it's moving (reducing the profile presented to relative wind). If the tail doesn't come up within a few seconds, it's an indication that something is wrong and to abort before the go/no go point.

2) OK, so the tail finally comes up 7 seconds in and the elevator is forward- but then ten seconds later the tailwheel drags on the ground, you can see the dirt plume. Unclear if this is caused by undulation of the runway or the pilot's attempt to rotate. The plume of dirt from the tailwheel continues all the way until the plane is airborne.

So how do we grade this takeoff? First, if the caption is correct and there is high density altitude, then the performance charts should be consulted and a decision made: either utilize a short field technique (full power prior to brake release utilizing every available inch of runway, even to the extent that the tailwheel is in the weeds at throttle-up, or more radical techniques such as a 90 degree turn once the airplane is rolling (have to be careful in a conventional gear airplane)-- or DONT TAKE OFF UNTIL BARO PRESSURE RISES, TEMPERATURE DROPS OR RELATIVE HUMIDITY FALLS.

Second, in terms of technique we can learn a lesson from the big jets-- maintain forward stick pressure until rotation speed + 10 knots and then affirmatively rotate the aircraft. You can see in the final seconds that the pilot is commanding back stick, and all he's doing is increasing the angle of attack and the corresponding drag, as well as the drag from the tailwheel hitting the ground.

Recommend removal from active flight status until remedial training complete.
