Resources
Learn to reada number.
The product explains its own measurements, but some notions deserve more room. Guides, a glossary, the model changelog and the state of the sources: everything is public, including when something does not work.
The last band is where the model is weakest. It stays on the page for that reason.
Reading guides
What 61% actually means, how to read a percentile, why a sound analysis can still be wrong. Eight short guides, no mathematics.
Glossary
Each term explained twice: the definition, then the plain rewording, with an example and the place to see it in the app.
Model changelog
Every model change is dated and justified — often by the disproved analysis that triggered it. A model that never changes is a model that never learns.
State of the sources
The data sources, their freshness and their incidents of the last twenty-four hours — published continuously.
For teachers
The demonstration datasets and the methodology can be used in class, without an account.
Support
From any match page, sharing attaches the computation identifier to your message: we answer about that precise match.
