Gas absorbtion modal should not care what the pressure is in the tank,
only thing it needs to know is what is in that tank and you have to
tell it that before the dive

Some of the AI computers make a correction if you are working hard, this is
gauged by your air consumption, but I believe that this is only the same as
normal common sense conservatism too.

When I used an AI computer, I liked to have the gauge just to double check
at the start of the dive that they were both singing from the same
songsheet. I invariably used the gauge during the dive anyway as it is much
quicker to check at a glance.

Correction! No. Fudge Yes.

They can not possibly know why your air consumption is what it is
because the parameters are way beyond what the computer can know.
Without knowing why your consumption is high any adjustment is a fudge
