Me either. I didn't meet a developer using phenidone as the only reducer, but metol has a number of such a formulation. Frankly I think there will be not enough phenidone in the first bath to be absorbed by the emulsion to properly develop the film in the second bath.

Example: Anneman Gainer developer
To 100ml of hot triethanolamine (TEA) add
* Phenidone 3.75g
* Metol 0.63g
* Borax 1.88g
* Vitamin C 2.25g
