Developing times - 4X5 TXP/rodinal/Unicolor drum

I am about to develop my first 4x5 TXP negs and I am seeking advice on times for N development in rodinal. Processing will be done in a Unicolor drum processor.

What are your suggested developing times @ 1:50 and 1:100 and at what temperatures? How many ML of developer do you use at these dilutions in the Unicolor drum?

Thanks in advance.

Try looking at Agfa's data sheets

They are pretty good and accurate and an extremely good starting point.
