That worked out well. What's your dilution for selenium toning?

I am confused. Using ISO 32 the negative is thin but ISO 80, which is not the real film speed, provided a denser, more usable negative? This needs some 'splaining, please.

Two different developers for starters. The XTol 1+1 negative should have been developed longer, but I used my time that I tested well over a year ago with this film, and it always gave me excellent, workable negatives. If PC-512 packs more punch than XTol.

It seems to me that if a film is properly tested in two different developers, it can be developed to the same contrast index in both developers even if one developer packs more of a punch. The resulting effective film speed may be different, but matching the CIs should be achievable.

I'm enjoying the videos.

Yes, it's easy to match the DR's, but there will always be subtle differences, such as grain, sharpness, tonal rendition. PC-512 gives similar rendition to XTol, but with slightly more apparent grain. Thanks, Stephen!
