Yeah I wasn't sure how big a factor the tire wear would be so I pitted too early but the boost let me catch up fairly quickly.
I really like the sound of the points system for the series. My suggestion would be that since these races are decided near the end, why not break them up into two shorter races for the series? Racing bumper to bumper for an hour and a half is fun in a spot race but for the sake of long-term competition, I think it would be better to have two races scored independently. Like some of the touring car series out there do. You also have to give points for position - I'm sure it was implied - nobody mentioned it yet.
I'm thinking a thirty minute practice/qualifying to get everyone in the room and ready followed by two roughly forty minute races with a ten minute break in between (with no cars allowed on track?). That would make for a two hour event.
I like BTCC's point system. Points for position, 1 point for pole position in the first race, 1 point for fastest lap in each race and 1 point for having lead a lap in each race. In their old format for 10 drivers, the points went 15-12-10-8-6-5-4-3-2-1 plus bonus points. Applied to our series as I've suggested, a driver could earn a maximum 37 points over the course of two races. Except for ours because it's going to be so competitive, we should probably bump the points for leading a lap up to 2 or 3 to make for a stronger incentive.
Also, the series should be limited to 10 or 12 drivers because there was enough bumping and banging with 6 people last night.
