The negative for the picture you mention was developed in Windisch Catechol, a pyro based developer. The reducing agent in this formula is pyrocatechin, which is different from the reducer in PMK, pyrogallol. Pyrocatechin is also the reducer in Pyrocat HD which many fine printers use for semi-stand or minimal agitation development.

It's not a case of stand development OR pyro development; I know many photographers who get beautiful results using stand development WITH pyro.
