Ah, the classic "pit like the more you do it, the more lieky you are to get your eyes pecked out". I think it was the Miata enduro where this strategy was taken to hilarious means. I had T2s on my crappy little mazda, and the computer had somthing way too soft. He started as #1, and was a tiny bit faster than me in most the laps, but he pitted just about every 4 laps. I on the other hand pitted twice the entire race...since miatas are light and have next to no downforce or speed or resistance or any of that, I could go 15-20 laps before going red.
