just the other day, on Race C, it was the one-make with the IsoRivolta on Maggiore GP.....terrible car, but I love the track.
I was qualifying top 3 every time, race after race. I could never catch the guys in front until one race they both spun out and I passed with 2 laps to go. Right around that time my girlfriend came in the room and asked if I was about ready to eat. I said "yeah just a couple more laps, I'm in the lead and should win this if I don't screw it up."
Well, I screwed it up. Had about a 5s gap between me and the guy who recovered his spinout, and I put one rear wheel in the dirt on the final turn, instant spin, could not recover. I got 3rd. That's only the latest of many of my throw-aways. It does happen less often these days though, as I've gotten a lot better and more consistent.
Edit: also yesterday at Nations Cup, Gr.2 @ Interlagos....I went into the pits after lap 7 of 16, I filled what I thought was enough gas (hint: I didn't) then came out of the pits in 4th and I noticed I had jumped the guy who was right in front of me before pitting. That should have been my sign. It wasn't until the last lap that I learned I didn't have enough fuel. I was holding 4th position pretty good, but for almost the entire last lap I had to run on fuel map 6 just to make it to the end. Fortunately I only gave up one spot and finished 5th, but still kicking myself now as 4th should have been mine.
