That is exactly what I am referring to.
He did a test and Dektol was giving very unpredictable result. I am not saying it cannot be done. I am sure many people have done that way, and it works in a sense that any developer develops latent images... But some are more stuitalbe to the particular use than others.
The situation is rather contradictory: while you need inter-positive with less density, which means less development time, less agitation, and more diluted developer. But you will also need to get even tones without mottling or excessive edge effects which require longer development time, more agitation, and stronger developer. Dektol is a developer with a high alkalinity due to amount of carbonate which makes difficult for these requirements to meet at the same time.
D-76 works a little better, and his LC-1 works really nice. It is a two-part developer and control the contrast by changing the ratio of two parts.
