I have sound files of me clicking my noid at over 31 CPS's, but we already knew the gun could do that. Once you incorporate the mass of the bolt, and the ram, cycles become much slower. I've had my gun cycling over 26 CPS though. Easily. After that though it starts to become half cycles, or my reg just wasn't recharging fast enough. Havn't tried since I got my detonator.
Here is the sound files. This guy that was interested in my Wrath wanted to hear them, but he got Agg's wrath instead because I didnt' want an xbox and an Ion.
