one ms is 1/1000 of a second, right?
So that's 7/1000 seconds. A game running at 60 fps has frames that "last" for 1/60 of a second.
I was surprised at the 7 ms at first, cause it never got lower than that. But if my math is correct, it can pass things many times back and forth within one frame (not that you'd ever want to). And that's only if the 7 ms is correct and it's not just the timer function that doesn't get any more exact.

dark_samurai: I'd be honored if you did! Maybe you should mention that it's a "third party" demo though, cause I still cannot quarantee for any correctness. And if you want to, change the sentence in the readme saying that Anet.h should go in the work folder to a sentencce saying it should go into includes folder, cause I wrote that wrong and I'll have a hard time changing it (it's not my server that it's hosted on atm).
