Clandestino
It is NOT 'intended' to compromise the elevator's authority. Its intent, as you well know, is arguably out of place in Alternate LAW 2, when Pitch is unprotected, and the Pilot hasn't a clear knowledge of the actions of the THS.
Further, in a recovery, what the THS does more than anything, is FRUSTRATE the Elevator's authority, and you also know that.
To Stall in DIRECT? or ALTERNATE? Like clandestino, a toss up.
This I do know. To recover from a STALL? given 447's data, DIRECT. WHY? Because without a fully up THS, the elevators could not have kept her in the STALL (caveat: pending a final decision by BEA re: CG). She'd have dropped her nose, something these gents were not granted as a cue that STALL was underway, (and just broken).
If, after the nose dropped, the PF kept holding full back, a slow repetition of the same thing. Then if he eventually did not figure things out, perhaps the rollercoaster may have prompted one or the other worthies to sit down.
