Sounds like you are consistent with your usage of terms, and I understand the logic and the motivation.

I would just caution that it's fairly idiosyncratic - plenty of people out there don't use the word "power" the way you do. For example, here is how Paul Graham talks about the "power" of programming languages: http://www.paulgraham.com/avg.html

Just saying, as consistent as your definitions are internally, being too rigid about it may hinder your ability to communicate with others in the field. Good luck buddy <3
