Put it this way. This dm8.
For argument sake. It has shot 1 box of paint every month since first purchased new. Which would be about right. Averaging what I have used it. Its a 5 year old marker. So has fired 120,000 plus.
It was re-annoed 3years ago and not a mark on it still.
Billy wing bolt fitted same time. Which has probably done 72000 shots. And is as clean and shiney as the day I fitted it.
I dont agree with striping it down after everytime I use it. As that just wears out bolt heads and threads. Imo. What it does get is service to dye's recommendation. Wiped clean after every use and stored in its case.
Anyone who knows me. Will say its like new and still fires flawless. Only time I have had problems. Was due to the nut behind the trigger. Buy not fitting new battery or trying to get an extra days play out before servicing.
So what I'm getting at is shot count is not really worth the programming time to put in to board. It's really down to care and recommended maintenance. If you look after your equipment. It will look after you. I.e. keep it clean and serviced. Then when you turn up to site. Its just hopper on, bottle on and crono. Then sit back and laugh at all the muppets that miss games or run about trying to fix there marker or need to borrow one at start of day.
