I think, what he is saying is... since he has done most of the reading and experiments, that actually save us having to go through the same amount of literature.

I know personally, when i do those type of reading, they all give a very conflicting opinion. Example: Vitamin C. Some say 250mg, another say you need 3000mg/day (or even as far as 20000mg/day). Almost every piece of medical advice that i read always have counter-argument. It's so hard to know which one is working without experiment. Even then, i'm not sure how long u need to carry the experiment.
