Nice to see some data. It does feel a bit cherrypicked (or alternatively maybe an advertisement for how nice the routes could be if more than a few blocks had bus lanes) to only consider a tiny portion of the overall route. Anecdotally (I (try to) take the 77 a lot) that route seems to get bunched up and come more like two to three busses every 30 minutes than what the actual schedule says, and it's faster to walk between Cameron and Porter in practice about half the time.

What I would like to see instead of bus travel time as a metric is person travel time - something like given a random distribution of humans arriving at the bus stop, how long on average does it take, including waiting for the bus, to get to a given destination.
