Data note: 7 of the last 14 days were not collected live. No collection ran on Oct 22–Oct 28, or a later run refilled those days at once. Every hype score is measured against the 14 days before it and those days are thin, so the scores, the stages and the week-over-week theme trends may read higher than they are until they leave that window on Nov 12.
