This reminds me of freshman year high school we did the presidents challenge in PE. One of the things was getting timed at the 50yd dash at the beginning and end of the year to see fitness improvement. For the second one everyone except one guy's times were worse so gym coach spent 10 minutes ripping our asses. How lazy we are to all be sand bagging and not giving full effort. How hard a worker the one guy was to improve. There were several athletes in the class but they all did worse.

Turns out he marked off 50 meters instead and doing the math sure enough most of our times would be slightly better. He did apologize in his old ball coach way.
