The information on the page is updated every 15-20 seconds while you're watching it, and is based on information retrieved directly out of the X-System which, every time a race restarts, outputs the track cycle timing info for the page to use. It's as granular as I can make it without going overboard and wasting resources.

It's not intended to be correct to the second, or even really to the race. It should be accurate to within 1 race or so, but as soon as the crowd votes to restart a race before the track cycle kicks in, it's just page decoration from there on.

But the problem is that no one is going to join the server if it's empty. So in order to get more people there I join and race. Erm... I mean drive around. Might as well gain something from it.
How else would a driver like me have gotten Gold
