Fomapan 400 4x5 , pyrocat and tank development?

[Murgo]

Hi. Does anyone develop Fomapan 400 4x5 in pyrocat HD using a tank process? What kind of time and agitation do you use? I have a basic AP (Paterson style) round daylight tank with a 3D-printed insert for 4x5 in which the film is loaded folded "taco style". I have up till now used Cinestill DF96 to develop my films and just starting with Pyrocat. I have so far developed one roll of Fomapan 400 in 120 with it using a 14.5 minute developing time and 30 sec initial+5 sec every minute agitation I found in the Massive dev chart and it turned out ok but I wonder if I should do the same with 4x5 or is some other routine better?

Also, I've so far metered for ISO100 in 4x5 as it seems to give ok density developed in DF96. Metering at 400 gave way too thin negatives. Should i expose differently with Pyrocat, many seem to use ISO200?

Sorry if this has been already discussed, I couldn't find anything with the search function.
