Oh I didnt read your theory btw, because I wanted to answer on my own before seeing it. Don't like to read too much so I can be unbiased. In my opinion you want to steal most often from mediumish stacks as opposed to small and large ones. I thought this was a reasonably basic concept, but you seem to have given it a different name.

When you steal from a small stack they are pretty desperate, and will move allin a lot, whereas if they are a medium stack the risk/reward just isn't there a lot of the time. A large stack can reraise a lot for other reasons....as the chips they are raising often don't mean so much to them (although when you have 1900 in chips, its almost impossible for them to reraise on a bluff with the idea of folding, so theoretically its not that big a deal)
