For HP5+ DiXactol single-bath (compared to D-76 1:1) gives about a stop slower speed, big grain and high acutance (because of the big sharp grain) but doesn't resolve near as fine detail. It stains more brownish than PMK so shouldn't cause such extreme highlight compression when printing on VC paper.(posted 8809 days ago)After seeing such results, I didn't see any point in further testing.
Generally, two-bath developers give results that are fairly close with different films developed together or for the same time/temp/dilution. That's fairly close, as in printable, but certainly not the same. _Some_ pairs of films give essentially the same results when developed to the same specs in some developers while another film may be wildly different. It all depends on what films and what developers.
