The spring survey consists of 3 "phases", each of which I believe is 4
weeks long, for a total of 12 weeks for the whole survey (someone correct
me if I'm wrong).

However, I suspect the numbers posted by R&R are actually the Feb-Mar-Apr
and Mar-Apr-May Arbitrends, which include data from, but are not the same
as, the phases of the spring book.
