Results completely aside, it is important to realize many guys in the pack may have gained speed and dropped their lap time due to the draft.
We haven't had the issue too many times, and when we did we had the driver DQ themselves. Like everything else, progression needs to continue. Perhaps we need to look at a hard rule about what qualifies as a disqualify. It would certainly be difficult to monitor as a single steward, but this group has always been open about the racing and continues to hold the mind set that racing is priority one, winning comes some where after that. If we had the guideline of what constitutes the need to DQ yourself, it might help keep continuity.
Some thoughts:
1. Drivers placing in top 3 positions only, considered for running too fast = DQ
2. No more than 20 or 25% of the laps can be run under the target time within a half second
3. Draft needs to be considered...help me out on some details
4. Solo (non draft) lap under the half second grace period = auto DQ
May sound rough, may not be necessary, but I think it is worth revisiting, especially as we plan to "recreate" our league. I do have issues with my own guidelines...especially number 2. We have had some races where a driver may run half the laps at a tenth under the target. There is a lot of grey area, that is for sure.
