I am interested in using highly dilute developers (HC-110 / Rodinal, at dilutions of 1:100 or more) with sheet film in order to obtain a long smooth tonal range that successfully controls highlights. I recognise that this means very long development times - does anyone have a table of development times for this approach that I could use as an initial guide? I mainly use Tri-X, but might use FP4 for this purpose.

I develop Tri-X 4164 sheet film (ISO 320) at 16 minutes @ 70 degrees F in Rodinal 1:100 for N development, 12 minutes for N-1, 9 minutes for N-2, and 7 minutes for N-3. For roll film (mainly Delta 100 & 400) I use PMK.http://www.ravenvision.com/rvapeter.htm

I have some times for Rodinal at (1:100) on my site. See the Articles section: http://unblinkingeye.com.
