I'm going with a 9.
Because of the fact that no one had to mash somebody out of the way for position.
Good, hard racing by two excellent competitors with equal respect for one another. This is what it's really all about.
Being there, most of it was boring as hell in the middle of the race. I'm just glad they got all 400 miles in. Excellent final 30 laps. Overall: 6.5; Final 30 laps: 11.
