We're going tomorrow.
Jeff, we've timed autocrosses with cheap stopwatches from Walmart before. For hand-timing, it doesn't much matter what you use. They time to 1/100, but your hand accuracy is only good to about .05-.10, meaning that with the start and finish, you could be as much as 2/10ths off.
But, still, if I can't beat you by more than 2/10ths, what's the point?
(if you're confused, this post was actually made at about 11:30am... how it got a later time stamp we may never know!)
