2 OP: I understand where that question comes from but after a little insight, it is just plain silly.
Please walk with me, from 50% (1,05) up:
a) If you shoved TLs to TOGA/FLEX in an instant, the actual engine acceleration will follow the FADEC schedule.
b) If you move the TLs in a controlled fashion up, but always staying ahead of the N1 as the engine accelerates, the FADEC schedule is the same as a) above.
c) If you advance too slowly and restrict the acceleration, that's plain wrong.
a) or b) is the same, c) is mishandling. Headwind makes no difference.
