B. Compressed air stored in the pneumatic system, stored at a maximum pressure of 120 PSI in no more than four Clippard Instruments tanks. Extraneous lengths of pneumatic tubing shall not be used to increase the storage capacity of the air storage system.
C. A change in the altitude of the ROBOT center of gravity.
D. Storage achieved by deformation of ROBOT parts.

R72> In addition to the items included in the KOP, pneumatic system items specifically permitted on 2010 FRC ROBOTS include the following items...
A. One or two additional Clippard air storage tanks (Clippard Part Number AVT-32-16), equivalent to those provided in the kit. This means that up to four, and no more, Clippard air storage tanks can be used on the ROBOT.

And:
<R76> “Working” air pressure on the ROBOT must be no greater than 60psi. All working air must be provided through one primary Norgen adjustable pressure regulator.
A. All “working” pneumatic components (e.g. valves, cylinders, rotary actuators, etc.) must be downstream from this regulator.
B. Only the compressor, relief valve, pressure switch, pressure vent plug valve, pressure gauge, storage tanks, tubing, and connecting fittings may be in the high-pressure pneumatic circuit upstream from the regulator.

Yes Virginia, Inspectors know how much tubing is too much.

So if I understand it correctly, then we could use a large gas piston as a sort of accumulator, but only it has to be on the 60psi side of the regulator (not too big a deal, just half the energy). I haven't used pneumatics in years but I suppose that it is a way out if I need a bigger capacity than the 2 Clippards provide (and I have the weight to burn.)

Am I right?
