The EDMU has a bar per shot feature which I find works very well. Like now I have my Leshiy tuned to shoot about 6.3 bar a shot at 22fpe.

Thanks but surely the measurements you quoted would vary depending on the volume of the storage vessels?

Correct. A 250mm barrel with 41cc before the reg 13cc plenum. If you know your volume of the gun it's quite easy actually. The EDMU measures the pressure drop for each shot and on avg. So say you take 10 shots and it'll read the avg bar or psi per shot over those 10 shots. Or whatever your looking for. Then you can calculate it from there. I use this

That’s what I was looking for, thanks👍

This makes me think of a question? But I need to relate it to something I understand a little. When I use to work on high pressure circuit breakers one test that was done to evaluate performance and check for internal condition in-between rebuilds was air consumption per operation. To measure this we used a calibration gauge, operate the breaker, measuring pressure drop. While watching the gauge the pressure would rise a couple psi. After a minute or so. The pressure drop would be a larger number than the air consumption really was. Now here is my question. Does the same thing happen to airguns? Is that something that is happening making us think a regulator is slow at recovering? Any thoughts? Sorry if this was a stupid question because of the relation.
