Metrics

What do you want to understand about your study?

Fluorgan public metrics are organized by decision question. They separate prediction, observation, evidence, and missing data so study does not become decorative numbers.

Core questions

Start from the real doubt: would I remember now, am I available, how much work is coming, do my cards help, does my answer represent real recall, or has this content consolidated?

Local filter

The hub control only filters public cards by predefined themes. It collects no data, saves no choice, and sends no selected value to analytics.

Other signals

Lapses, difficulty, response distribution, evidence, and forecast add context to the main metrics when enough real data exists.

Would I remember now?

Retention compares an estimated lens with an observed lens. The estimate describes the current state; the observed view uses recent valid first review attempts; evidence indicates how much weight to give the reading.

How prepared am I for my goal?

Readiness combines memory, coverage, and deadline when the goal is defined well enough. It supports a study decision; it does not predict a grade or exam result.

How much work is coming?

Workload forecast places future demand beside declared capacity. It is a planning projection, not completed work.

Do my cards help or get in the way?

Card Health reads structural signals and, when evidence exists, behavioral signals for the current card version.

Does my answer represent real recall?

Recall Integrity separates remembering from effort so the next review reflects what happened during the attempt.

Has this content consolidated?

Consolidation represents accumulated evidence of greater stability. A historical milestone can remain true even if the current state later needs reinforcement.

Other signals you will find in Fluorgan

These signals add context to the main metrics when the underlying data is available; each answers a narrower question about your study.

Lapse / confirmed forgetting

Failure or successful recall within a valid first review attempt.

Difficulty / hard

High effort is not failure; it separates fragility from firm success.

Response distribution

Splits qualified responses without hiding an empty set.

Confidence

Sample and precision change the weight of a percentage.

Short/expanded forecast

Operational projection; future is not observation.
