Anyone try to increase the potassium hydroxide concentration in rodinol, and if any what where the results?

I'd expect it to make the concentrate stronger, but may cause problems with prec ipitates etc. Why do you want to do this?
To see what would happen
Take a look at this page, which has some important precautions about potassium hydroxide, but doesn't say what its function is exactly in Rodinal.

Potassium hydroxide is the alkaline agent in Rodinal. Increasing it will increase the activity of the developer, probably making it even more contrasty. I doubt you will see much difference from simply developing in Rodinal (1:25). My preference has always been to use Rodinal at higher dilutions such as 1:50 and 1:75, so I wouldn't bother with the hydroxide myself. But you never know until you try.
