Very nicely done! Was just checking a few stations where I commute, and compared the intuitions picked up about horrible / acceptable times, and line choices. Seems to match up to my experience, which makes the data-diving even more interesting. Also since those parts match, I can now look at other stations with a different eye, and based on the data have a feel for travelling there/through... Good stuff!
