CogSim, good catch on the PF never acknowledging the PNF statements. It certainly does seem to match a hypothesis that PF was fixated on the unitial WTF moment.
Clandestino, the initial nose down command was way before the THS was stuck at 13 degrees. That started about 35 seconds later in the sequence at 2:10:51. And as I read it 2:10:51 was the start of THS movement from 3 degrees to 13 degrees.
