Isn't the GO pass priced such that you buy it for everyone and then Caltrain hopes that peak usage isn't too high as a result? Which means you don't have enough data to evaluate if it's priced correctly or not. I bet Caltrain makes individual deals with Stanford and other large users that reflect actual usage.
