- Ranked fixes
Ranked fixes show points gained, hours saved and what each one assumes.
A fix is ranked by what it would win back, with its assumptions listed. It is a modelled estimate, never a promise.
How a fix is worked out
Points gained, rider-hours a year and a rough cost come from the cause’s measured loss and range. The rider-hours come from the cost measure. A list of assumptions is shown beside the fix.
How sure we are
How well a fix works is modelled and not yet calibrated against real outcomes, so no fix is ever above medium confidence.
Costs stay empty until they have a source
A unit cost with no source gives no cost, and the page says why. Nothing is estimated from memory.

Method version and change log
A published month never changes. If a method is revised, past months keep the method they were worked out with.
