I know that some of you use Rodinal at 1:100 dilution. Can someone give me a starting point for processing times with Tmax 100 (4x5), Delta 400 (4x5) and Agfa 25 (120).

I've no direct experience of this combination. The following sites don't include the exact combinations you want, but you may be able to extrapolate:

Rodinal @ 1:100

If you use Rodinal a such a high dilution, make sure to increase the total volume of developer solution by about 50% per roll (or sheet)to insure that there is enough stock developer for complete deveopment.

1:100 high dilution Rodinal is usually used to tame the high contrast of Kodak Technical Pan film. 1:100 6 minutes at 20 degree C.
