Post 302 crystallizes also. I ran strips with that baseline developer by mixing directly into water, but when I mixed it as a concentrate five days ago, it crystallized. Then I created more concentrates of various formulations, made a table of all concentrates I've ever mixed since January, and looked for patterns in the numbers. The result is yesterday's long posting, and the realization that D316 happened to hit the narrow usable window.
