How is day zero chosen? Unclear if this is a reasonable comparison.

  Yes, a very fair point. At the left when the tail is sooo thin, it's easy to move it left and right by quite a few days. When there aren't many cases, it's hard to choose a "day zero."

  It doesn't seem to say here, but in other analysis I've seen it as the day the 100 case threshold was crossed.
