The Drag Strip analyzer can be a very useful tool as well. Its very helpful for correcting raw track data for weather conditions. First I set up a baseline pass for a given combo on a given day. When I get home from a day at the track, I pull up that baseline pass, change the weather conditions in the file, then fiddle around a bit until the incrementals match up, print it out, write some notes on the hard copy, & store it in the log book. The print-out can be VERY useful at the track later on when you run into similar conditions, and its a really nice neat format.
