Through the first 3 rounds of this season Saturday morning sprint races have all been shortened to 5 laps (as they have been for several seasons), presumably to make room for the completion of the entire scheduled endurance races. By the third round last year we were back to running 6 laps for the LW classes but not this season.
My question is why haven't the endurance races been shortened to allow the Saturday morning sprints to reach the 6 lap race total?
I understand that there is a limited amount of daylight to get all scheduled races completed but I don't understand why only the sprints are shortened or why the endurance races aren't simply scheduled for, let's say, 5.5 hours rather 6..
