Standards and Progress

StrideSignal displays the A and B labels exactly as they appear in the loaded USA Track & Field - Paralympics standards source. They are published benchmarks used with the source's stated competition or ranking-list system. Meeting a displayed mark does not by itself guarantee entry, selection, eligibility, funding, or classification approval.

A standard must match the source authority, season, event, sport class, gender category, venue, and age group used by the athlete profile. StrideSignal does not substitute a different class, gender category, season, or event when a matching value is unavailable. Standards are stored as published values; official USA Para A and B marks are not estimated by StrideSignal.

Lower is better. The displayed progress is:

progress percent = standard time / athlete time * 100

Example: a 12.00-second performance compared with an 11.40-second standard is 11.40 / 12.00 * 100 = 95.00%. The athlete needs 12.00 - 11.40 = 0.60 seconds of improvement.

Higher is better. The displayed progress is:

progress percent = athlete distance / standard distance * 100

Example: a 5.70 m long jump compared with a 6.00 m standard is 5.70 / 6.00 * 100 = 95.00%. The athlete needs 6.00 - 5.70 = 0.30 m of improvement.

Only positive finite marks are calculated. Missing standards, missing performances, invalid units, incompatible classes, and excluded results display an explanation instead of zero, NaN, or infinity. Progress can exceed 100% after a standard is achieved. Displayed marks are rounded, but calculations retain full precision.
