Ilford Ortho Plus with either Pyrocat or FA-1027

[Tumbles]

I'm starting to get back into photography after the apocalypse followed by a one year work crisis. I got a bunch of Ilford Ortho Plus to photograph all the new spring vegetation. I'm needing to refresh most of my B&W chemicals, and the 2 developers I have on hand that aren't totally expired are Pyrocat HDC and FA-1027. The results I've gotten with these developers for FP4+ and HP5+ have been magical, so I want to see how Ortho Plus would respond.

For Pyrocat I found one time listed as 14.5min at 20C. The question I have with this, and all listed Pyrocat times, is if this is for minimal agitation or not? It seems a bit low for minimal agitation, where most times I see are around 20 minutes. I'm pretty committed to minimal agitation with Pyrocat.

With FA-1027 I can't find any times at all. Has anyone tried this? I may have to do some trail and error experimentation. Does anyone have any guidelines or suggestions of where to start with this?

i don't recall where I saw this or if it's indeed the case--perhaps more knowledgeable members on this forum can share their knowledge .... That said: FA-1027 may be nearly identical to Clayton F76+; if that is the case then use the MDC recommendations for FP4+ and HP5+ in Claytons F76+, standard dilution 1 + 9. I regularly process FP4+ (at 100 to 125 ASA) in F76+, 1 + 9, for 5 minutes at 24 degrees C, and HP5+ (at 400 ASA) for 6 minutes at 24 degrees C; I use the recommended agitation procedure, i.e., four inversions (10 seconds) every minute.

Comparing some of the FP4+ and Ortho times, it looks like FP4+ has development times that are a bit higher. Something like 8 vs 7.5 minutes. I think my starting point for testing will be 8.5 minutes, 1:14, at 20C.
