Totally agree, and certainly didn't mean to imply that it'd be a substitute for actual experience and advice, but for somebody who's trying to do some theoretical planning away from the track it is an interesting curiosity, like most of the models on that site, and might suggest some things to try if you're doing workouts on your own. It definitely deviates from the real world -- there's no way I can see to model complex conditions like track surface quality, wind direction, or just plain weirdness like the cracked pavement in turn 3 at Kissena, or the mini-cyclone that crops up in turn 4 at T-Town.
