You aren't in the GTP iRacing users directory so I can't look up your stats, but if you are averaging 9 incidents per race on these short sprint races, you are doing something wrong. It's as simple as that, it's not an insult towards you, please don't take it that way. A few incidents and occasional contact is expected, but not in every race. When I was going through rookie and D-class I was averaging less than 3 incidents per race for both road and oval. I didn't get many wins, but I almost always finished on the lead lap at least because I was rarely involved in accidents.
Just a couple suggestions here (you may already be doing these):
1) Look further ahead
2) Watch for driving patterns in the way the drivers both in front of and behind you.
3) Drive more defensively
4) If you see someone starting to spin or wrecking ahead of you, let off the gas immediately, move to one side of the track, cover your brake, and be prepared to change direction or go off track to avoid the accident.
When are most of your incidents occurring? Are they lap 1 or 2 crashes? Or later in the race? How are most of your incidents occurring? Rear ended? Sideswiped? Getting into cars that spin in front of you?
I really would like to help you, so like I said, don't take this as an insult to your driving skills, I'm trying to get you to continue iRacing because the more people we have who stick around the more official races we have and the larger fields we get to race with = more fun.
