Cooper Push-Ups: 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 protocol summary is checked against the Pennsylvania MPOETC one-minute full-body push-up directions, which identify the depth target, full extension, permitted rest position, and continuous hand/toe contact.
