FX-15, speed increasing?

greenspun.com : LUSENET : Large format photography : One Thread

I mixed my first batch of FX-15 and was expecting a speed increase, because of the Phenidone. Surprise, I got a speed decrease of one stop compared to D-76H. When developed to normal contrast, the EI that produced a Z 1 density was 125. I wonder if my mixing of the Phenidone was the problem. I had difficulty disolving it and had to heat the water (distilled) to almost boiling. Anyone tried this or other FX developers?
