Efficiency test math?

So, I did an efficiency test with my Valken Proton but I had 2148 (2009 after airing up) PSI in a 50ci tank. I'm trying to figure out how my math is and where I'd need to go in order to get a PSI/in3 at 4000 PSI and then the PSI per shot.

So far, I've got a basic equation for PSI per cubic inch which would be 4000/50= 80PSI per cubic inch. Is this correct?

If so, at 576 shots (I counted the paintballs before I did the test and had each pod labeled) off of a ~2000 fill doubled to reflect 1152 shots off of a ~4000 fill, would it be 1152/50=23.04 shots per cubic inch?

Finally, if both of those are correct, would it be safe to assume that it's roughly 80psi for 23.04 shots off of one cubic inch at 4000 PSI that could then be multiplied by the size in cubic inches of a tank? Meaning a 68/45 would be roughly 1550 shots per 68/45 filled to 4000 PSI?
