I don't know what the settings were, dnafwtbtitft. I just know that after 4 shots at a "jogging" pace, the Nerve "sprinted" all on it's own, with the mechanistic regularity that BL describes. I witnessed a couple of other clearly illegal guns, one of which kept on shooting about 2 ball per second into the ground as a plyer walked off the field. None of this stuff would have fooled R2D2 (as I shall henceforth refer to the NPPL's robot). There may have been loads of more subtle cheats around, but the Nerve, at least was not.
I have heard lots of people acused of having ramping guns, but as of right now, I am convinced that most of them were innocent. There are a few people I have watched play who may well have illegal programming, but I don't think it is as widespread as I suspected before. Maybe that is the sort of complacency that SP wants me to adopt, though...
It seems like PSP has bigger issues with non-semi automatic guns than the NPPL (surprise). I think that someone who wanted to get away with it could, but an irregular rhythm would need to be integrated into the cycling on an assisted firing mode to keep it from being apparent. I also think a non-obvious toggle (trigger activated?) would be required to get away with using it and getting away with it.
Just so I don't sound like I am bashing the PSP reflexively, I should say that pit safety was on the whole more carefully enforced than I expected.
