Done per the instructions, there should not be a loss of altitude.
The question is, will the nose
consistently drop to horizon only, and not below ? Every such maneuver I taught/made/saw being made resulted in a loss of altitude.
Especially since when countering MCAS, the crew will have a hard time "raising the nose well above the horizon"...
But I admint never having done that in an airliner.
