Mine is set for 9. Best way to set up goes like this. Set the COPS @ 10 & jam on the trigger. If you break a ball, roll down to the next setting (i.e. 9). Jam some more. If nothing breaks, try 10 again. If you break @ 10, go to 9 & fire just a little more. If nothing breaks, 9 is your setting. If you go back up to 10 & it doesn't break 10 will probabaly work (check again to make sure). The COPS will have to be checked once in a while as you use your gun and the sensor loosens up a bit. Once it gets too loose, take it to an Angel tech & have them re-seat it. With my setting, I've gotten up to 15 bps with no breaks (usually at 12 during games). Hope this helps.
