in quantity terms, the rough amount of shots per tank is this:
3000psi is usually times by 10 to get the shots per fill, ie a 1.1 will get 680 shots, 1.5 with 880 etc etc
4.5kpsi is times by 15, so 68CU (1.1) will get 1020 etc etc
this is just a rough estimate, remember most markers will do better than this, like a nexus cocker gets 1750 off a 1.1 and an evolve matrix gets from 1600-2000 etc etc
