There was definitely some messed up things within the games timing system last week.
Drivers who were on the lead lap were having their races ended.
I think it might be a smart idea to have the racing set to a # of laps for tomorrow - solely because something was obviously not right with the game when it forced JW and Neutty to finish effectively making it look like they were a lap down when really they weren't (not saying it affected them, but what if JW and Neutty were racing for position, I think one of them had underfilled on fuel and was worried they weren't going to make another lap).
IF we do a # of laps instead of a time to mitigate any potential weirdness going on with the games internal system - remember than the # of laps won't really matter for the slower cars as they'll effectively be multiple laps down depending on the length of the circuit.
All in all, I'm not sure how you want to do it - but there was definitely something going on last week - and the game really fukced it.
