It's too bad that I don't have time to go to the range until Friday! Oh well, I took it to the garage instead and shot 112 JSB Exacts over the chrony. A 180bar fill gave me about 100 consistent shots at an average velocity of 810fps (12.299ft/lbs, according to chairgun 2). By the 112th shot it was down to 773.3fps.
I don't yet know if I'm going to tune it up at all or not. I'm happy with 810fps for now, and I certainly like getting 100+ (I'll try filling it to 190bar and 200 bar later) consistent shots from one fill!
I can't wait to shoot some paper, this gun feels SOOO nice.
