Air consumption with Altaros regulator. Good or bad?

Allegedly set at 135 bar. Definitely spits JSB 18.1's at an average of 861 for 50 shots. I filled to 3K, shot 1 mag (10 shots) refilled and listened for when it clicked open (have a Hill MKIII) According to Hill gauge, (guns stays right at or slightly above 100 bar depending on fill. pushing it to 3200psi raises it ever so slightly between green and yellow, Rainstorm I model, I think reg leaks a little) So, according to Hill gauge, rifle uses exactly 400PSI per 10 shots.
I don't know tube CC size and I don't think 40psi per shot is the right way to define it. Even with a regulator, is 400psi per 10 shots good at 29.8FTLBS 861FPS?
This doesn't sound bad to me, 50 shots would take me from 3K to 2K. I've never had a regulated rifle though (this is a .22 Evanix Rainstorm I with Altaros) so I don't know if this is as good as it gets or not.
Have had rifle for about 3 days. I just filled to exactly 3K. Will let it sit for 7 days in same environment (check pressure again in 2 hours as I filled when cold from outside) and check to see if it dropped at all.
All help, advice is greatly appreciated.
