Just a little note on the tracker. Various things have changed.
Because this track has 4 sectors, we changed the sector images (nothing big). I just noticed that the sector is sometimes displayed wrong (car in sector 3 displayed as being in sector 4), but this is nothing serious.
Also, I changed the way the difference to the car ahead is calculated. Instead of displaying "+1 lap", it only shows the difference in time.
For example:
Car #1 is on lap 65 and finished lap 62 6m32s ago
Car #2 is on lap 63 and finished lap 62 0m15s ago
Then the difference shown will be 6m17s. So in effect, it uses data of 6 minutes ago, so the bigger the gap, the larger the deviation. However, the larger the gap, the less relevant an exact measure is, so this should not be a big problem.
The advantage of this way, is that it gives more information. The old system said "+1 lap", but this can be 1 lap and 3 seconds (so right behind the car in front) or 1 lap and 2 minutes (so maybe right in front of the car in front, so nearly 2 laps behind). This time difference might also be more usefull when calculating pitstop strategies.
More improvement suggestions are always welcome
