The EFCS *targets* Alpha Max with the stick fully aft - it doesn't *guarantee* it.
A properly flown alpha max demo will deliver alpha max, what make you think the FCS would not comply ?

I disagree on that as well. For the PF to maintain full back stick for a while is not of all comfort. If he wants to concentrate outside, I find it practicable for the PNF to stay inside and manage thrust versus v/s.

That's why it is surprising in the Habsheim case, as alpha max was set at 17.5 deg and thrust reached 83% N1, the elevator had no intention to deliver anything closer than 2.5 deg short of alpha max ...
