Oh, but there can be.

Here only the two-bath technique can help and the greater the difference in the way the two developers work the more variable the results can be - and nothing beats the Lith + Amidol combination. "
We do a number of 2-bath processes on my lith workshops, with the first being lith developer - but the concept is the same. The results just a bit more apparent.
Incidentally, I second the endorsement of amidol. For 2 bath with Lith my preference for technical and practical reasons is for Weston's amidol, also available in kit form from 'The Formulary'. Using it as a 2 bath and a waterbath with the very warm Fomatone MG is quality of the resulting duotone prints is wonderful.
