It would be good to get something like an average lap time per track.

Best way to generate this might be take the last 100 laps times, drop the top and bottom 5% and average the rest to get the time. The fastest and slowest being dropped to give a better time and also to ignore out laps mid race etc being included.

some days I just can't get to my pb's, so my average times would be a good benchmark I guess..
