Commuter Experiment - Update

I got rather tired of updating the blog everyday... pretty much saying the same thing every day. "Had to wait for the bus today... there were mechanical problems on the train... etc" So I figured I would try to do a weekly update instead of daily. I've also been away from the experiment for a while because my wife had a baby and I've been off work for a few weeks. But I'm back now and the experiment is back in force (with a few minor hiccups when I forget to start the timer when I leave the house or leave work.) so I don't have a complete unbroken set of data points, but I have enough data points to start to show a trend and an average. So I will present some findings today from the 23 days worth of data that I have so far. (Counting this morning's commute).

So my morning commute is averaging about 3 minutes shorter than my afternoon commute. However the morning commute on Mondays and Thursdays are longer than my afternoon commutes on those days. My Friday morning commutes are almost 10 minutes shorter than the afternoon commutes. These are some pretty interesting trends, we will see how they trends into the future as winter approaches. Somehow I think there will be some pretty big outliers that will develop in the winter. As memory serves me, there are usually 5 or 6 days (when the weather drops below -30C) that the C-Train service really suffers and the wait times for transit are measures in hours rather than minutes. Should be interesting.
