Quick side note, since I always had the wrong impression about this when people talked about it until I experimented myself:
If the target remains aligned with the front sight during such misalignment, yes the shots will still be -0 or A zone.
If the target remains aligned with the rear sight during such misalignment, the shots will be way off.
Personally, when I draw too fast and have misaligned sights, it's because the front sight is in the wrong place, while the rear sight is roughly correct. Anatomically this makes sense since the rear sight is right over the grip, whereas the front sight is way out on a stick essentially, being steered around. In this case, the misalignment demo isn't particularly relevant and is actually quite misleading. The moral of the story is that the alignment of the front sight with the target is paramount. The rest of sight alignment is auxiliary.
