My read on that is that braking would have been initiated at 425 feet (when the brain registered the OMG, and she hit the mushroom), and full skidding occured in the last 125 feet. At the purported speeds on that section on automatic control, that would have been a not unreasonable distance from the initial emergency application to full locked up skidding. Once the site distance have been released this should be resolved. Note the skidmarks were on the track.
