Sorry, Chuckroast haven't seen your post earlier. Unfortunately Perplexity answer is absolutely useless here:
The Beutler developer itself is typically made from two stock solutions (A and B) mixed with water in a 1:1:8 ratio. DK-50 diluted in a similar manner aims to achieve comparable results
Generally I stay away from full stand developer. This is totally "fooling around" project for me, let's see what can be done.
Some 35+ years ago when I first time made DK-50 it reminded me a lot of HC110 I used back then. I made it to try it with ORWO NP-7 BW motion picture negative film. Now I tried it with Kodak 5222. I don't mind a touch more contrast and grain.
I do a fair amount of open tank processing and that involves 2 liters of working solution. For Beutler's, that would be 200ml each of A & B added to 1600ml of water. So, I premixed a liter each part so as to have plenty on hand.
My next excursion here will be to further dilute it perhaps 100:100:1800 and do semistand for an hour. That should be interesting...
To follow up ... My first, and likely only, attempt at this was not good. Buetler's is not a good candidate for stand, I don't think. It tends toward drag and - as a pretty aggressive version of a compensating developer, it really flattens highlights and midtones if you don't agitate.
