Weevil,
I hope you get a look at this and give me your opinion. I did get the Valken reg to 1500. On my set up I have a straight pull on the hammer and I can add weights to increase or decrease the hammer strike. This morning I started at the 1500 with my lightest 7 g weight. To see what would happen I put on a heavy 54 g weight and got about 15% more velocity so I ran with that weight. I ran the shots down to 1000 psig as indicated on the bottle. I got 39 shots to 1000 with a total FPE of 1144 fp. At the same 1500 psig reg and the 3000 psi fill, using the light 7 g weight down to 1000 as indicated on the bottle gauge, I got 66 shots for a whopping (relatively whopping, that is) 2211 FPE! So I guess one would say that this is a much more efficient arrangement. The pic shows where the bottle reg shows the drop off the reg (and at this value point, the bottle gauge and the gauge I'm using to call the reg pressure are very much in alignment) and I think that's true because you can see the resulting rise and fall of the shot velocity as the valve first opens more due to the reduced pressure in the valve and then falls as the pressure drops even more. I don't know if a person is ever "done" fooling around with this kind of thing but this looks like a pretty good place to be at this point.
