Checkable

Statements that can be checked

The one distinction the first two figures cannot see.

9 notes in this part

A statement is checkable here if a reader can confirm it without taking the publisher's word. The line is drawn by hand, once, and declared.

Definition

The checkable count runs from none to all, so each page is a family of shapes. The record's size follows, and the addition fits in one line.

Recount

Publishing something verifiable does nothing for a reader who never meets it, and the gap between the two fractions is this part's subject.

Analysis

With half of a set checkable and half of it met, exactly one content is blind — on every page where that arrangement occurs, whatever its size.

Recount

With one verifiable statement published, the blind share is exactly the fraction of the set a reader missed. No combinatorics survive.

Reference

At the far end of the third column nothing is blind and every opening is verifiable. Forty-four shapes sit there, one on every page.

Reference

The record counts how many statements are checkable and never which. A real limit, the reason the strokes are laid out as they are, and unfixable.

Caution

Checkable, unverifiable and unreached are distinguished by how the line is drawn rather than by its colour, because colour is lost first.

Reference

The checkable count is a judgement, not a measurement. Closing the part by working out how far the figures move when it is off by one.
