I agree with Air Rabbit that after thousands of landings you know what is normal acceleration and deceleration. As a brand new captain on an empty 737 I was the first landing at RNO at 6 AM after a snow storm that closed the airport the night before. Everything seemed normal until I came out of reverse at 80 knots when my deceleration stopped with max braking. Going back to max reverse got us stopped but there was no doubt in my mind that the braking action was nil. Only reverse kept us from going off the end of the runway. No, we never got a braking report from the tower.
