Nice article. I wonder though if the the distance to 'on time' is really normally distributed - did you test this?

I'd expect it to be short-tailed on the 'early' end and long-tailed on the 'late' end. For instance, missing a connection can throw you off by half an hour, and there's no symmetric gain available. In parts of a problem that are like this, it's better to look at the frequencies of the various cases than a continuous distribution.
