Cooper 300 m Run: Source and Display Method

The current numeric table was manually corrected before this review and is preserved exactly. Automated OCR and reviewer readings of scanned images are used to flag differences, not to overwrite a published value. Permanent checks lock the reviewed data and verify its age-page and trend copies.

The field procedure is checked against the Indiana Law Enforcement Academy 300 m protocol and Pennsylvania MPOETC directions. Those sources specify a flat measured course, maximal effort, timing to a tenth of a second, and a walking cooldown.
