Hi J-S, Looks like a very cool resource. Have you ever been able to put it to any practical use? I could see this being helpful, but I don't see it removing all of the randomness :) There are always undiscovered bugs lurking here and there. I, too, would love to see driver writers aiming for 100% scores on these tests. -- Terry Welsh www.reallyslick.com
