Fair enough Irish Blues. I work in a field that has its own vernacular, but many of the same words have laymen's meanings too. So, people (including colleagues) can use language sloppily when it should have a more precise definition. I empathize with your irritation.
I guess I was just conforming to the general usage around here, since I knew everyone would know what I meant. And I stand by the use of that phrase "regression to the mean" as an abstraction, not intended to mean a specific statistic, but rather as a general sense of "performing more in line with expected performance based on level of play". I guess maybe our language doesn't have enough colorful ways to say that.
I'm not one to cite advanced metrics much at all, although I find them interesting. I'm also not one who lazily dismisses them without bothering to try to understand what is being measured (or attempted to be measured).
