Four ways to index 16,384 characters, weighed

Each bar is what the structure retains, computed from its own shape rather than from a serialisation, on English-like of 16,384 characters. The dashed rule is the packed text at 81,920 bits. All four return the same occurrences for the same pattern; they differ in size by 147 times. One of them cannot answer at all unless the text is kept beside it, and its bar includes that text.

Drawn at 700 × 204, wide on the page. Everything above is what index-size returns with no arguments; the caption is the generator's own, computed from the numbers in the drawing rather than written beside it.

14 essays call index-size. The drawing above is what it returns with no arguments at all; every call below passes it something, because a placement that passes nothing draws whichever member of the family the generator happens to default to rather than the one its essay argues about — which is what optcheck and figfill exist to catch.
