Rule D33. Each trend is compared with the publisher’s next two editions: kept under the same name (persisted), kept under a new name (renamed), dropped (faded), or dropped and brought back later (recycled). This measures the publisher’s own consistency, not whether a trend came true, and is never a hit rate. 55 trends are not graded because a following edition was only partly captured (D36).
57%
persisted, 1564 of 2749 (55% to 59%)
20%
renamed, 558 of 2749 (19% to 22%)
0%
recycled, 8 of 2749 (0% to 1%)
23%
faded, 619 of 2749 (21% to 24%)
Still open (fewer than two later editions): 1381. Audit of the agreed rename checks: 8 checked, 13% residual error.
