- A rating belongs to a named system, discipline, series, division, and time period. Values from different contexts may not be comparable.
- Recent match count, field strength, result quality, and the model's uncertainty affect how much confidence a rating deserves.
- A rating can summarize competitive evidence; it cannot fully describe safety, sportsmanship, coaching ability, equipment knowledge, or performance in another discipline.
- Imported or corrected results may change the evidence behind a rating. Review provenance and update time when the distinction matters.
- Use a trend and the underlying matches to guide practice. Do not chase small movements that may reflect ordinary result variance.
Expected result
You can identify what a rating covers, how much evidence supports it, and which conclusions it does not justify.
