After many years of using a few different pyro developers, I've caught the itch to try WD2H. I found an old LFPF thread where John posted the correct formula and showed that he used 25ml A + 25ml B + 1600ml water to tray develop FP4+. Working out the dilution ratio here it's: 1+1+64. That's a somewhat odd dilution to my mind and he may have done this to extend development time. Is anybody else using this ratio or do you stick to the normal 1+1+50 of standard WD2D+?

Thanks for the help.
