I agree @Dragonwhisky which is why I sort of lay back and watch things unfold in these reverse grid races. My closest opponents are usually right in front of me and we're all waiting in line to get around a slower driver ahead. When cars are running single file you don't get any help with the draft. If you succumb to the fact you will not be able to out race someone you'll let the adrenaline pass and simply put your car in a position to capitalize on mistakes rather than force passes that are not clean or earned. Now that I'm in a division among peers, passing is no longer the goal. Staying close is my goal as well as preventing others from getting opportunities to pass me. In practice, one of the D1 drivers said my car was as wide as the track. I held off about 4 cars at Spa that night by being fast in the only two places on the track that count: Turn 1+Eau Rouge, and Turn 15 (Stavelot). If you build a 2-3 car gap exiting those turns, you eliminate the draft...and that eliminates any clean passing as long as you put your car on the right part of the track for the rest of the turns. I think I was running defensive 2:28s among drivers that could run 2:25-2:26.
