Revision rotation — what the colours mean

The number and the date on each card are what was measured. The colour is what the portion is estimated to be worth now: the last score decayed by how long it has gone unverified, at roughly 4% a week.

That is why a 99 unheard for five months sits in the red, while a 74 heard this week only asks for a look — one is unverified, the other is merely mid. Green means settled, yellow due a look, orange overdue, red urgent. A dashed grey card was never verified at all, so there is nothing to estimate from.

Decay counts from the last full recitation, not the last visit, so a spot test does not reset the clock. A score shown with a dotted underline marks exactly that case: the portion was seen more recently than it was scored.

Pace & retention

The day-one score measures reading as much as recall. What matters is how the same passage scores when it comes back for revision — the change on return.

Consolidation

One return tells you a passage survived. The sequence tells you whether it is bedding in. A passage climbing 61 → 73 → 81 is consolidating; one sitting at 77 → 79 → 76 across six weeks is not, and no single number would show the difference.

Passages are grouped by overlapping range, so a portion revised across slightly different bounds still reads as one thread.

Time to graduate

Median rather than mean, because one passage that never graduated would drag an average out of shape. A portion running far past the median is the one to look at — it is being revised without settling.

Rotation cycle

Two portions heard the same number of times can be in completely different condition. What matters is the gap between hearings, not the count.

Spot vs full recitation

These two aren't the same scale. Being dropped into a random ayah is harder than continuing a flow, so spot scores run lower almost everywhere. Read the gap as a pattern across portions, not as a portion "failing".

Condition over time

Each point is one passage on one day, scored from the mistakes recorded in it. Stages are never pooled — a first-pass score and a long-settled revision score mean different things, so each has its own line.

Fewer than four points is shown as points with no trend line: too little to call a direction.

What's stuck, what's fixed

Resolved means the ayah was heard again at least twice afterwards without a mistake — not merely that it hasn't come up since.

Work on these next

Ranked by severity, how often the same spot recurs, and how recent it is — so a mistake made three times last week outranks a worse one made once, months ago.
