What exactly defines a wet race? The other day I was in a race in which it rained during qualifying. The rain stopped prior to the race. At the start we had 0.7 mm of water on the track. I would consider this a wet race, but one driver was disqualified because of the tire rule (he used inters and one dry compound). So it appears IGP rules considered this a dry race.
Can someone help me figure this out?
