Let me calculate. Ram is 80*100 if I recall correctly. @ 55 bar this swallows 27.625 liters of room temperature gaseous CO2.
A 20 oz bottle contains 307 liters of gas. 11 actions in ideal circumstances. 8 actions is realistic with a good setup.

Venting white clouds means loss of liquid CO2, less actions, and rapid pressuredrop and freezing in the system.

One of the reasons Beauty 8 has such a huge heatsink....
