While I reached 9600 steps during one day of the past two weeks, my average accomplishment is not so high.
However, IF I were to keep a 'running average' of my average walking achievements, each day I don't achieve 10000 steps/day makes the 10000 steps/day AVERAGE more difficult (if not impossible) to achieve.
I wonder what we do about psychological discounting if one's AVERAGE performance is a public statistic.
