Subject: [Leica] Looooong development

Has anyone tried something along the lines of this:

I've been toying with the idea of using diluted XTOL for very long
development, with minimal agitation.  I'm thinking along the lines of
XTOL at 1+3 or higher dilutions (perhaps up to 1+10), using the normal
inversion agitation for the first 30 seconds, and then just letting it
sit there for perhaps 30-60 minutes without any agitation at all (at
20C).

Why?  Well, for one, I wouldn't have to be present all the time to
shake the tank ;)  Also, there seem to be virtues in using diluted XTOL
(higher film speed, less grain, smoother tonal range) from what I've
read on the web.

I remember reading about some other developer that was used without
agitation for very long periods of time and just thought I'd ask if
anyone has any experience of this.
