When I regged my AA400 carbine I ended up eventually after a lot of trial and testing with 114 shots before it dropped off the reg (Lane). I would expect the 200 to reach 80 shots at least.
Did you get any instructions with it? I had to open up the transfer port, remove the firing pot, increase valve preload a bit then use a shorter stronger hammer spring, I didn't have to but also made a a longer/lighter hammer. The reg was set to 105bar.
