Standard Deviation and z-score in plain English

[ego]

I can explain how, where and when to bet for regression toward the mean (( if anyone is interested ))

That 68.3% of the time the divergence would be one SD or less. Either side of the MEAN.
That 95% of the time the divergence would be 2 SD's or less. Either side of the MEAN.
That 99.7% of the time the divergence would be 3 SD's or less. Either side of the MEAN.
That only 0.3% of the time would the divergence exceed 3 SD's
