I do regret not including the player's current sector, as it would probably have made things a bit easier for you guys. I tried to do as little manipulation on the data as possible before copying it into shared memory, to avoid a potential maintenance nightmare. What you're seeing is pretty much coming straight from our various subsystems, but that makes it easy to miss various surrounding state needed to make sense of it. I did seem to make some sense out of the sector stuff in my testing though. I'll try and document it as clearly as possible. Also, I can confirm that it's not properly recording invalid lap times in race sessions, @Craig. Seems like this is a bug that's slipped through somehow, and not something we intended to change.
