The point isn't that anyone expects to shoot 1000 rounds in an SD/HD situation, the point is that this is a way to show up minor issues that might not otherwise be noted at all.IF I have had to use 1000 rounds in a firefight I would have already either called 911 or Ellington Field for an airstrike.
A typical malfunction rate for a good quality gun with factory magazines and ammunition is perhaps 3 rounds in 1000. If you get to the range once or twice a month to shoot 50-100 rounds and have a couple of guns, you might note a malfunction once or twice in a YEAR. At that sort of "rate", unless you keep very stringent records you probably won't even take notice of the malfunction.
A lot of people assume that shooting 1000 rounds without cleaning will somehow cause the situation to be more stressing. In the general case that is not true--in fact, in both matches so far, the number of malfunctions per stage has DECREASED over the course of the match. In other words, as the guns get MORE rounds through them and get more fouling buildup, they get MORE reliable in general. I suspect at some point that would cease to be true, but up to 1000 rounds, it doesn't seem to be an issue.
The point of shooting a LOT of rounds in a relatively short time while stringent records are being kept is that you can show up issues that might otherwise go unnoticed. The bigger point is that the information is useful to other people who actually take the time to look at the results instead of just dismissing it out of hand.
