I sort of know what you mean - I think what I mean is that you spend less time looking at the docs to accomplish basic stuff. For instance I spent a lot of time reading the codeigniter docs 6 months ago to even get something working, now I go back to remind myself of things every now and then. When I read the docs now it is more to get a deeper understanding of what is going on and working out how to improve what I have done.

Maybe I should say that you spend less time in the docs not knowing what is going on.
