The problem with the claims of flow rates is that they typically ignore the critical element of temperature. We do not always operate at ambient temp. Our robot compressors are usually too hot to touch for back-to-back matches, meaning it is tougher to compress air than they typical duty cycle compressor. I suspect that the AndyMark compressor, with a longer duty cycle, may do better in a typical FRC environment given its better duty cycle, but I'd like to see some numbers.

This how we do our final pneumatics tests to know if we need another tank, and it seems to work for that purpose. I don't know what it'll tell us about different compressors though:
Fill up 4 tanks -> 5 minute break -> run testbed for 2 minutes -> Record Pressure
-> 2 minute break -> fill up 4 tanks -> 2 minute break -> run testbed for 2 minutes -> Record Pressure
-> 2 minute break -> fill up 4 tanks -> 2 minute break -> run testbed for 2 minutes -> Record Pressure
