# Bortz Improvement League

Canonical HTML source: https://longevityworldcup.com/league/bortz-improvement

Requires at least two eligible bortz results. Rank by latest eligible bortz age minus worst eligible bortz age, then bortz age reduction, earlier date of birth and athlete name. This differs from improvement from the first result.

Field size: 5. Current standings, not a completed-season result.

## Field definitions and dates

- Scores are in years; lower and more negative values rank higher. Sorting uses unrounded scores; tables show two decimals. Rank is within the named view; Ultimate rank is a separate column.
- Age reduction is biological age minus chronological age at the selected test. Crowd age reduction uses the current-image median minus current chronological age.
- Lowest clock ages and their test dates refer to that clock's selected result. Not available means no eligible value was recorded, not zero.
- facts_changed_at_utc records an observed change to this document's facts. Unknown means no historical change date has been verified. Cache refresh and response-generation times are not publication or test dates.
- Competition rules: https://longevityworldcup.com/ruleset. Completed-season results: https://longevityworldcup.com/history.
