Thanks, Ron. So I was not nuts. I am glad that I gave up on getting any closer to neutral and white when I did.
I did play with an old ep/2 kit with it before trying the RA-4 adaptation. The developer agent bottle looked mollasses, so I tosed in some dry CD-3 (or was that CD-4 - no notes at hand here as I type) of a weight to correspond to the g/l concentration of an old BJP or somewhere else formula. The reslts were not a lot different from the RA-4, but different filtration was need, as would be expected, to get to the same-ish off white with yellow stain.
