some chrony numbers with valve swap

in a previous thread i mentioned about buying the parts from airforce for the condor valve and switching them into my ss valve. everything is just a swap fit. here are some numbers that i just shot and i was wondering if you all could comment on it. i.e. is it typical?
pw setting at 12, th at .050, starting pressure: 2600 psi, ending 2300 psi

919.5 910.8 900.9 907.4 877.5 880.9 878.9 853.3 845.3 850.5
lo 845.3 hi 919.5 ave 882.5 es 741.8 sd 26.62

828.6 826.2 853.0 808.3 822.6 805.7 831.0 796.0 839.8 813.5
lo 796.0 hi 853.0 ave 822.5 es 57.05 sd 17.05

as i said, starting pressure? 2600 psi, ending pressure 2300 psi
20 shots kodiak match .25 cal 24″ bbl

seems to me like it isn’t using a whole lot of air per shot, but i don’t know all the math behind the science.

what do you all think?
