Yukala,

Seasoned's comments;

BOTH work best when you have an idea of what you want.
BOTH can work at a fast speed with no real concious thought.
BOTH can bring back related points of interest, etc...
BOTH could be pretty much devoid of conscious effort.

Like brain, I hoped that that first item would not be as important with PR.

I think the key word here is balance. I do not believe in effort just for effort's sake. I think way too much effort is just as counterproductive as little or no effort. My perception based on brain's posts and all the best to brain i wish him well, my perception is that brain wanted to be able to go through massive textbooks with little or no effort and be able to know everything in the textbook with litte or no effort.

I think you get what you put into it. You put little or practically nothing you get very little. You put a lot into it you get a lot more but the key again balance you reach the point of diminishing returns if you go overboard.

Take care.
