Great information.

From my limited experience, the shaft volume is not insignificant for most FRC applications. We have found that the smaller the cylinder the more significant it becomes.

That said, the more complex sheet does shut off the compressor when the maximum storage pressure is attained.

Again from limited experience, over the past two years we have trimmed weight to maximize onboard storage and still run below 60 psi with the compressor running full time.
The two years prior the compressor was on for short bursts at a time. So, both situations are good to have accounted for.
Did I mention, thank you for tabulating this for us?
