Response to Compensating development with PMK ?

Sometimes PMK is subject to uneven development when there is insufficient agitation, though I did a semi-stand development with it once with no problems. Generally, though, I would not classify it as a compensating developer. However, pyrocatechin-based developers are known for their extreme compensating effects. Ansel gives a formula in THE NEGATIVE that I have used many times. There is also a new formula called Pyrocat-HD that uses phenidone and pyrocatechin--it was specifically formulated as a substitute for PMK, rather than as a compensating developer, but I have used it successfully with little or no agitation. I have both formulas on my site at unblinkingeye.com.
