I have a copy of an old Camera and Darkroom that contains an article about the differences that can be achieved in a negative through various dillutions of HC110. I'll have to find the article but the main point was that at least for HC 110 a better control of the negative was achieved through controlling dillutions rather then relying on increase/decrease of developing time to control expansion/contraction.
I never meant to say anything else. I thought the "developing time being of no concern" statement covered that.
All things being equal - here I would submit that they are not - it would be better to use a weaker strength and extend times - BUT!! a higher concentration - emphasizing concentration itself and forgetting about time -
might be desirable for a certain effect.
