Every factor and standard on this site is transcribed from a published source, cited where it is used, and dated. This page says exactly which sources, and where the site refuses to produce a number at all.
An invented number on a recruiting page is worse than no number, because a 16-year-old will plan around it. So where a governing body publishes a figure, this site transcribes it and cites it. Where nobody publishes one, the site says nobody publishes one.
Two conventions, both published, and they disagree. NFHS adds 0.24 seconds at every race distance. Track & Field News and Athletic.net band the correction by distance and add nothing at all at 800m and above. Both require the hand time to be rounded up to the next tenth before the factor is applied, which is the step most quoted conversions get wrong. The converter runs both so you can see the difference.
From the peer-reviewed Moinat, Ruiz and Fuentes-Vega (2018) model, fitted on 150,169 elite and sub-elite results, with the coefficients copied from the authors' own published calculator. No federation adjusts a result for wind, so the output is for understanding what a mark is worth, never for claiming a time you did not record.
The NCAA's own published flat, banked and undersized factors, transcribed from the USTFCCCA chart and cited with its URL on the conversion page. The site refuses to convert toward an undersized track, because that direction is not published and inverting a published factor is not the same as having one.
World Athletics records a mark to the lesser centimeter and never rounds up. A calculator rounding to the nearest value will hand you 6.25m where the results sheet says 6.24m, so the converters here round the way the sport rounds.
The division bands on the standards pages come from a published recruiting service, cross-checked against a second one, and are dated on each page. They are not published by the NCAA, and the pages say so. Programs and conferences vary widely, so they orient you rather than rule you out.
The running-event projections use the World Masters Athletics age factors, transcribed and cited on each page. Jumps, throws and hurdles have no published youth factors, so their curve is TrackReels' own: the USATF championship meet record for each Junior Olympic age division, for the U20 championships and for the open championships, each division record taken as a fraction of the open record and interpolated between divisions. It is labeled as a TrackReels derivation wherever it appears, the records and the implement changes are printed on each page, and it is not an official standard of any body. The one adjustment the derivation makes, holding the curve flat where a younger division's record beats an older one with the same equipment, is stated on the page it applies to.
It will not publish an "average time by age": nobody publishes one, and every table claiming to is either scraped from meet results, which only include athletes who competed, or invented. It will not convert between distances where the ratio is the wrong model. It will not rank a mark beyond the world record.
Articles on this site are drafted with AI assistance and then edited and fact-checked before publishing; the data, factors and standards are transcribed by hand from the sources named above. If you find an error, send it to support@trackreels.io and it will be corrected and the change dated on the page.
