Cringe ... zero vacuum is one atmosphere, one Bar, or around 14.7 pounds
per square inch absolute, it is no vacuum at all.
The most complete vacuum you can produce will still only create a
pressure differential of 14.7 pounds per square inch at sea level, or
one atmoshphere.

"zero-zero" in my view means "absolute vacuum", or -14.7 psig.....
It would probably be better for you to define an absolute vacuum as 0
psi instead of -14.7 psig. Your way depends on your altitude, the
barometric pressure.
