I think there is vital information not presented in the report. In particular the position of the thrust levers is only given at a couple of points. We know PF dialled in a lower speed because of turbulence and shortly afterwards AT disengaged. How long after this point did the PF touch the throttle levers to increase thrust? I don't think we are told. Later, after the first stall warning, the engine levers at at TOGA. It would be very useful to see a graph of engine N1 over the whole period.
