Race Control
Fixed the ttRating computation so that it does not underflow below 0.
The Time Trial UI while driving will no longer erroneously say that a sequence is in progress when it may have actually been interrupted by some of the more strict laptime checks we now do.
We relaxed the recently made stricter best laptime filtering a little so that laps with connection problems that don’t affect timing will be properly considered again.
The rule checking for cars that have entered a closed pit lane can now cope with people who are having connection problems without incorrectly issuing black flags when they reappear.
Also: Added Darlington setups to the Chevy Silverado.
