I am looking for some options, but I really cannot find them.

I am looking for an administration-app for insim, to keep track of really long (several hours) of racing. They must exist ?
Take track of laptimes, pitstops, some stats, players in cars, and shift-p and disconnects (keeping track of runned laps).

Any tips?

Do you think about app for 16h race with stats on Website? I'm creating app with this functions but now it's only first version implements TOC and pitstops. Any times and dsc, pits don't work (user lost's lap's in app).
