Personal record
Fastest time for timed events; greatest mark for distance or height events.
METHODOLOGY
Every calculation should be easy to challenge.
StrideSignal favors short formulas, visible assumptions, and explicit labels over black-box scoring.
Season best
The best performance in the selected calendar year using the same event direction rule.
Yearly average
Arithmetic mean of all saved performances for an event in a calendar year.
Improvement
Timed: previous average minus current average. Field: current average minus previous average.
Target progress
Timed: target ÷ current × 100. Field: current ÷ target × 100.
Target difference
Timed: current minus target. Field: target minus current.
Wind estimate
Moinat, Fabius & Emanuel (2018) zero-wind formulas for the 100m, 200m, long jump, and triple jump. Estimates only; not validated specifically for para classifications.
Consistency
Population standard deviation divided by the mean of comparable results, shown as observed variation rather than a prediction.
Next-season projection
A least-squares line through seasonal bests, extended one season. The displayed range is the mean absolute historical residual, not a confidence interval or guarantee.
Calculated ranking
One best published result per athlete inside the chosen gender, class, event, age, level, season, and location filters. Never labeled official.
Official entered marks stay visible.
An adjusted estimate is displayed beside a raw mark and never overwrites it.
Time and field marks improve in opposite directions.
Lower times are better. Greater distances and heights are better. Every comparison uses that rule.
Official, calculated, estimated, and entered are distinct.
Labels travel with values so a coach or athlete can see what each number means.
