Only tropes with at least 30 counted mentions in each twelve-week band, in genres holding at least 500 trope mentions in each band. Without those floors a trope that went from two mentions to forty tops this table with a four-figure percentage, and that is not a trend — it is a small number moving.
It is a count. Every mention figure on these pages is rows we hold, over a window we name, from sources we name — and each readout shows you the week-by-week table those mentions add up from, so you can check the arithmetic yourself. Nothing is modelled, extrapolated or rounded up for effect, and every figure carries the date it was counted.
It is not a sales forecast. Demand-signal mentions is not the same thing as money, and a trope readers shout about is not automatically a trope that sells — that depends on the price, the shelf and the competition in your lane, which is what a Tropesmith Map is for. It is also not a complete census of the internet: it is our corpus, and where a genre is thin the page says so instead of filling the gap.
