methodology.
Every score is computed from public data by one published formula: percentiles all the way down, no hand-tuned caps, no opaque model. This page renders directly from the same formula definition the scoring engine executes, so what you read here is what runs.
the four steps
- 1metric percentiles
Every raw metric becomes its percentile rank over the entire pool, claimed and unclaimed alike: the share of the pool with a smaller value, ties counting half.
- 2dimension scores
Each dimension is the plain average of its metric percentiles.
- 3source sub-scores
A source’s sub-score is the weighted sum of its dimension scores, using the published weights below.
- 4headline
Sub-scores are sorted descending, weighted 1, ½, ¼, …, and summed into a composite; the headline 0–100 is the composite’s percentile rank over the whole pool.

Line thickness is the weight. This diagram is generated from the formula definition, so when the formula changes, it redraws itself.
worked example
Every number below is computed by the same engine that scores real profiles, so you can check the arithmetic yourself.

versioning
Formula versions are frozen: recalibrating anything (weights, metrics, scales) is a new version, and every score snapshot records the version that produced it. History is never silently rewritten.
Seeded profiles carry provisional scores until their first real computation; claiming a profile computes it from live data immediately.
Wondering what the number means for you rather than how it is built? Why your score moved, whether it can be gamed, what is stored about you? The FAQ answers those in plain language.
