The number of guys pulling 41 laps after round 4 is up to 15 now. Still Bertin holds onto the number 1 spot. Held in controlled practise. Holding in the quals. I'd say it'd be a real upset if he were to lose.
They are telecasting the race at: http://www.radiophenomena.it/. Hit "Live streaming" and there is a guy talking in Italian about the race. You could hear the cars buzz by in the background. Man, I wish I understood Italian.
Looking at the 3'rd round it looks like Bertin is the guy to beat and it looks like nobody can. Unless he gets knocked out, he'll win and Mugen will ask themselves how on earth did they lose when they had almost 7 of 10 cars.
