I have an Excel spreadsheet documenting every pass I've ever made in my Corvette(minus one pass where I misplaced the slip) with every breakdown of the slip, density altitude for each pass, modifications/tire setup for each pass, and a small note describing the run. Am I crazy or does anyone else do it too?
I've got some slips in my glove compartment, old pants, some in a box full of random parts, on my desk, in my closet, and I think I saw one in my trunk the other day.
