Sorry for the delay Peter. As mentioned I am using the Ilford Warm Tone Developer. I am using Ilford Chemistry for the entire process. I mix the developer 1:9. I started developing in trays so I could pull the paper when I was ready. After doing this for 12 sheets I was realizing no big advantage to analyzing each image under a weak red safelight. So now I am using 4x5 tanks like these. LINK. So far the development time seems good at 2 minutes. I dip the film in and agitate by moving the film holder up and down for the first 15 seconds. This is done in the dark (safelight on) without the cover on the developing tank. I then agitate every 15 seconds for 5 seconds. The film holder is pulled up to drain at 1:55. This is a bit messy. The film is then transferred to a stop tank and a fix tank. I wash in a tray made for washing prints. Temperature is room temp. About 76ºF
I am considering increasing my exposure time in bright sun to 2.5 minutes and bringing my development time down to one minute or maybe slightly less. If you shoot film these may not sound like good numbers but from previous experiments I think it may be worth a try with this paper to reduce the contrast slightly. I gladly welcome thoughts / feedback. The best way to learn is from each other.
