Legal personal and season best
Fastest legal, known-comparable time or greatest legal, known-comparable field mark. Missing or assisted conditions remain visible as an all-conditions best instead.
METHODOLOGY
Every calculation should be easy to challenge.
StrideSignal explains what each number means, which results were used, and where an estimate has limits.
Season summary
Median, top-three median, interquartile range, unique-result count, and meet count. A season is not ranked from fewer than three comparable results.
Recent versus established
A recent weighted level is compared with the median of every earlier stored exact-date meet result when at least three recent and five earlier results exist. It is not a readiness or fatigue score.
Competition exposure
Recorded starts, competition days, and meets. This is not training volume or total workload.
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.
All-history consistency
Robust log-scale variation across every stored exact-date result. At least five marks are required for the repeatability statistic. It does not describe health, readiness, or improvement.
Short-term projection
Every positive non-excluded stored mark contributes to a 30- or 90-day estimate. Exact dates enter rolling-origin candidate selection; coarse dates enter a robust anchor without an invented day. Sparse estimates are preliminary and the range is model spread, not a probability interval or promise.
Relationship evidence
Training-test and race records are paired only by exact date within the stated window. Coefficients require at least 10 pairs and strength descriptions require at least 20.
USA Para standard progress
Only USA Track & Field Para A, B, and VMAA publications are used. Event, event-specific class, sex, season, venue, and published age scope must match. Open marks shown to a youth athlete are labeled Open references, and missing standards are not estimated.
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.
