Rubics

I haven't made any rubics but I have used many. It seems that many have some simularities in their descriptions. For example, level 1 (worst), no performance in the task, level 2, some performance but still lacking, level 3, reasonable performance, level 4 good performance, level 5 excellent usage.
It seems as though the best rubics will work on outlining and highlightening so that it is easier to use. I notice that most rubics don't play with fonts to make them more usable. To be honest, once you have used rubics enough, you really just need the sections. Or is it beneficial to be verbose in outlining each section?
