So I finally developed my first negatives since high school, some 18 years ago. I have three different developers: pyrocat-HD, rodinal (or at least Photographer's Formulary paraminophenol), and some D-76 (well, close...Lauder Chemical formula 76). Wanting to run before I could crawl, I'd decided to do some stand development with the pyrocat and the rodinal. I grabbed three exposed rolls of Promax 400 35mm, some cheap no-name film I wanted ot practice on, two from my Canon and one from my wife's cheapo point-n-shoot, and developed them. The results were...surprising.

Note: all these scans are with the same settings and no manipulation. I tried to grab frame numbers as a standard density reference. They weren't scanned to be used, but for comparison. No complaining about dust or hairs!

D-76 D-76, 1:1 for 11 min, agitated for 30 sec, then 5 sec every 30 sec thereafter.

This is from my wife's point-n-shoot. Looks a little overexposed...maybe the camera is set for 1/100 sec shutter? To my untrained eye, the density looks "decent".

Pyrocat-HDPyrocat-HD, 1:1:200, 5 minute presoak in water, agitated for 60 sec, then stand for 45 minutes.

You can definitely see the stain here, but the density seems a little thin. There's no real black blacks in this negative, even in the frame number.

This negative looks even thinner! What happened here?

So it seems to me like the stand development, while at the right dilution, didn't have enough chemical in total to get the job done. These were all developed in single-spool stainless steel tanks. Perhaps a single roll in a double tank would work better?

More experiments and reports back later!
