If you're getting less then you've probably got the silver transfer port fitted or your bleeding air each shot from around the breech area. Hopefully not trying to teach you how to suck eggs
....there should be a small blast of air from the top of the breech (where the small black stabiliser latch is) but not from the bottom. if there is then a new breech or transfer port o ring is required, a shim might be required under the transfer port or the closing of the barrel to the breech isn't positive enough.
Forgive me if I'm being stupid. If a regulators job is to deliver a measured amount of air I assume that releasing the trigger delivers this regulated amount of air the barrel via the transfer port so wouldn't a leak between the seal and breech bolt affect the velocity rather than the amount of air used? I'm only querying this as I seem to get though a lot of air.
