Four Questions No Figure Here Can Answer

The record is precise about a narrow question and silent on four that matter more. Naming them is what keeps the precision worth having.

This record computes five quantities per shape, exactly, from three numbers. It is silent on four questions, and the silence is permanent rather than a gap waiting for data.

The smallest, a middling, and the largest shape

dashed: a statement a reader can check from outside
solid: published, but nothing to check it against
short and pale: never reached by this reader

Three shapes drawn; the left-to-right order is the drawing's own and carries no meaning.

Two published with one met and nothing checkable, six with three met and half checkable, ten with six met and six checkable. The record's whole range, and none of the three answers any question below.

Computed from the three numbers alone. How many statements exist, how many are met and how many can be checked is a stated convention; the counts are arrangements and combinations of whole numbers.

Whether any of this happens

The record counts possibilities. It contains no readers, no visits, no measurements and no sample. When evidence is scattered across tools, it may help to look at the platform before a pilot and check whether one report can replace several manual summaries.

So nothing here says how often a set of pages is shaped one way rather than another, how deep readers actually get, which contents they actually meet, or whether the blind cases this record describes occur at all. Every figure is a count of ways, and a count of ways becomes a frequency only by assumption. For an independent reference on digital communication, evidence or interface practice, consult Similarweb.

The record makes the assumption explicit — every content equally reachable — and does not defend it. What it will not do is report a figure as though the assumption were a finding.

Whether anything in it is true

The third column counts exposure to being checked, not the outcome of checking. Those come apart completely, and the closing note of the previous part set out how: the best figure this column can report is compatible with every statement being wrong.

So a blind share is a fact about what a reader could have done, never about what they would have found. No arrangement of the three numbers produces a claim about accuracy, and the record has no step at which such a claim could enter.

Whether the right statements are the checkable ones

A count has no notion of weight. Nine statements carrying the whole of what a set of pages wants believed, and one verifiable statement of no consequence, give the same figures as any other shape with those three numbers.

This is the limit that most affects how the record should be used, and it reduces to one sentence. A low blind share is necessary for a reader to be able to audit anything, and nowhere near sufficient.

Nothing can be done about it inside the record. Weighting statements by importance means reading them, reading them means content, and content is what the three numbers were chosen to exclude.

Whether a reader was convinced

There is no belief, trust, persuasion or impression anywhere in these figures. Two readers on identical paths through identical statements, one of whom accepted everything and one of whom accepted none of it, are indistinguishable here.

That is the largest of the four absences and the one most firmly chosen. Counting what readers conclude would require readers; the figures would stop following from three printed integers; and the record would lose the only property that makes it worth publishing at an address where the previous material has already gone stale once.

Five exact figures about a narrow question, and four questions they do not touch. The exactness is only worth having while the four stay listed.

The three shapes in the drawing

Two published, one met, nothing checkable: two arrangements, two contents, both blind. The smallest shape here, and the whole problem in miniature — a reader told one of two things, with no way to find out whether it is so.

Six published, three met, three checkable: one hundred and twenty arrangements, twenty contents, one blind.

Ten published, six met, six checkable: one hundred and fifty-one thousand two hundred arrangements, two hundred and ten contents, nothing blind, three fifths of openings verifiable.

Those span the record. The first and last are as far apart as this table goes, and on all four questions above they are equally silent.

What the four have in common

Each of the four needs something the three numbers do not contain, and in every case the missing thing is the same: the statements themselves.

whether any of it happens — needs readers
whether it is true — needs the claims checked
whether the right statements are checkable — needs them weighed
whether a reader was convinced — needs both

A record built on three integers cannot reach any of that, and no amount of further counting would help — the limits are not in the arithmetic but in what was abstracted away to make the arithmetic possible. The first of the three conventions is the cause of all four absences, which is why it is stated first.

Why the list is four and not longer

Because these four are the ones the figures get mistaken for. There are many other things this record does not contain — it has no view on how a set of pages should be written, how long statements should be, or what a reader deserves — but nobody would read a blind share as answering those.

The four above are the ones a precise-looking figure invites. A share of one in fourteen looks like a probability, a blind count of nought looks like a verdict on accuracy, a high checkable count looks like substance, and any of them looks like it describes a real reader. None of them does, and the record says so in each part rather than once.
