Air usage question?

I did too...but I used the measurements of the tank to get CI from here:
And used the "Gas Hog" setting. Figure the Double Trouble probably isn't that bad but oh well.

Volume of gas at atmospheric pressure = (cylinder volume) x (cylinder pressure) / (atmospheric pressure)
I calculated the internal volume of air in CF as 1.247 considering that atmospheric pressure is 14.7 PSI.
This gave me 2151 ci approximately. Not sure if this is correct, so if anyone knows if this is wrong please let me know.
At this volume, the calculator in the link already given states that this tank would yield approximately 52,988 shots on "Average".

At 6,000psi(I'm going to do the logical thing and say that since 3,000psi yields 10shots per cu inch and 4,500psi yeilds 15, then 6,000psi must yield 20), I'm going to say that your tank should fire about 43,000 shots with a standard efficiency gun. 22.5 cases. Lets give it a 10% downgrade for the A5 and say 39,000ish. 19.5 cases of paint.
Now, if you are down to 1800psi and we have to assume that you stop firing at around 600 with most guns, then I will(probably mistakenly) assume that you have a range of 5400psi to work with(from 600-6,000psi). Of that 5400psi range, 4200 was used, or around 78%. So if you used 78% of your available working air, then I would say that around 30,420 shots were fired. 15 cases or so. I could be WAAAY off but it seems pretty logical for a full day of crankage on a DT. I know I could run through that much if I had a thick enough wallet.
EDIT: I got the exact same numbers for internal volume as Matt
1.247 x 12^3=2154
