Hi Conso, I think you are looking at the wrong end of the incident.. The error occurred 2 1/2 to 3 minutes before the take-off roll.
The left AoA Sensor starts to give erroneous data during the taxi run, maybe caused by strong tail-winds bashing the AoA Vane in the wrong direction.
From that point on, until 8 1/2 minutes later the flight was not viable.
