Rating Levels and Competency

Is anyone familiar with any kind of generalized approximations of the kinds of competencies that are necessary in order to play at given levels? It goes without saying that the competencies aren't necessarily definitive nor universally accepted. But in general, I would like to see something that attempts to flesh out competencies from low to high. So maybe group the ratings with a spread of 250 starting at 1000 and provide the typical competencies seen at such playing levels. Possibly the spread might need to be more granular at certain levels. I have to imagine someone has taken a shot at doing something like this before. Although one may be far from a particular rating, I could see some benefit in knowing what to expect down the road. Any recommendations would be greatly appreciated.
