How much of the plenum is used?

I really have no idea how much of a plenum like 60-110cc is used when firing. I know there are variables like dwell, hs, sub 12 or fac etc but ...I wonder if an airgun is tuned to standard velocities for a given pellet like 18.1 in .22 and going for 900 fps how much of a 110 cc plenum is emptied when fired? It can't be the whole thing on a modest tune and reg setting and having had to fire several shots to empty even smaller plenums made me wonder.
