It's an old trick, if your gun is too hot at chrono, then the player will leave, turn the Hop-up off, then re-chrono and be just under. This has caused many fields to make chronographing with the Hop-up on, or off, depending on the preference, mandatory.
In my opinion, they shouldn't be touching your hop-up themselves, but they should be keeping everyone honest.
ďREALITY IS LIKE A STONE. TO MANY ITíS HARD AND COLD, THEY CANíT HUG IT OR EAT IT, IT ONLY FRUSTERATES THEM AND DOESNíT DO THEM MUCH GOOD. TO OTHERS ITíS STRONG AND DEPENDABLE, YOU CAN BUILD WITH IT, BUILD UPON IT, OR WORK WITH IT, ALSO USE IT TO SMASH PEOPLE IN THE FACE.Ē
