Excellent video @Tominco
That clearly shows how a perfect regulator works

"kris"that's not how most real pcps work, by adding extra fitting and the gauge you added lot more volume. In my guns, when i shoot it, the prechamber empties, your gauge needle barely moves maybe it is in glycering that's why. I guess it is due to extra large volume OR you must have some very small apertures in the gauge so it is restricting the flow. most of PCPs have quite small prechambers. maybe the impact is different. no idea

regarding the shotstrings, I think it would be more interesting to see few results with long wait between shots versus few shots fired fast right after the long wait ones.
does it make sense? what I mean is this may explain some guys have wide spread from shot to shot, or when a follow up shot is a miss. typically yes when the gun is tuned super efficient/ for shotcount so the hammer is weak for the set regulator output yes.

Most people would agree that tuning a regulated pcp to completely dump the chamber is not how you want it tuned. By dumping the whole chamber you make it very inefficient and defeat the purpose of regulating it and you would be better off with out the regulator. 

A regulator thats working correctly and a pcp propperly tuned for the regulator will fill instantly. If you have to wait on shots you need to correctly tune the pcp or replace the regulator cause its faulty.

My original idea was to use a section of high pressure hose with the gauge on the end. But, I thought that would be waaay to much added volume for any reliable accuracy. Some high pressure lines may flex as well which could throw things off. One way I could have run this better would have been an elbow instead of the tee. I figured the hard fittings would act as a reservoir'd chamber extension and have minimal effect on the functionality of the reg. It did increase the size of the chamber through so, I guess that would mean that the reg recharges the chamber even faster than what I was able to show! Even better! 
It showed me what I wanted to see and I would not recommend doing this to anyone. It was a LOT of strain on those itty bitty threads, IMO. I'm happy to be able to share it with you guys.
