You're measuring with a micrometer, marking with chalk and cutting with an axe. I agree with all your numbers, more or less, now ... show me an SPG that makes that all meaningful. 1160 PSI, 830 PSI, really?
The Safety Stop RB should read 3*2* (15/33+1) = 8.7 cu ft
it has a typo, but I'm afraid to edit it as the editor removes all spacing and results in a mess. Yes in practice you don't need to bother with the last two digits in the psi, just round up to nearest hundred.
