You were certainly very lucky with the Ferrari   overall Kevan's Corvette had the fastest lap times over most of the rounds.

How can that be right then? Deciding a winner from a set of questionable results leavers a bad taste.

There is nothing questionable about the results, your car on the last Round had the same race time but had a slower "Fastest lap", so the additional point for a tie breaker is awarded to the car with the "fastest lap time"
