You know it's funny how you can read something and not really get it, then 
find another source with the same information (slightly different wording) 
and the light bulb goes on!!!!! ..... anyway for the benifit of others who 
might have had the same disconnect as I did.

http://www.siggraph.org/education/materials/HyperGraph/color/gamma_correction/gamma_intro.html

I case this wraps and breaks the link, I googled "gamma correction tutorial" 
.... the SigGraph passage was the top hit.

I really wanted to argue 2.5 vs 2.2 as I had arrived at 2.5 (using the 
example in the docs) and had been using that forever. I just didn't feel I 
knew enough about it to present my case .... well it's a moot point now as 
(haha) I get it!

Cheers
