Left stick down descent

No worries, pull that throttle down all the way until you reach desired altitude!!!!!!!!!!!!

I always come in hot full down then kiss land it. No problems at all ever p3p, p4 owner

Good to know. I've been a chicken $hit to try it.

I feel the same. Because I don't want beak it

Which begs the question, what if the altitude isn't measuring correctly and you decide to hold down the throttle to land it, and it shuts off 100 feet high in the air?

It will land faster than normal.

Seriously, an in-flight barometer failure is pretty catastrophic since the P4 will try to hold steady barometric altitude regardless of flight mode.

A 'stuck' barometer and 3 seconds of throttle down would probably shut down the motors. There was another thread where the logs showed a barometer failure producing negative altitude readings. The P4 tried to correct by going up at full throttle and was never seen again.

What is the margin for error on detecting the altitude change?

If you simply have your barometer reading a little off, that would make no difference.
If your barometer is as screwed that it would create the problem you describe in the hypothetical scenario, you would have a lot of problems simply flying anyway.
So the answer is ... you won't find yourself in this situation.
