Hi!
@newtorf: I developed some Ilford HP4+ last night (Rodinal 1+25, 9 mins, really good results) and I listened to the interval "chirp". I think a "double chirp", just a touch louder, would be an improvement!
@adso: Hmm. Currently each recipe is specific to a given temperature, the onus is really on the person using it to duplicate the recipe and change the time as needed. In addition to a dilution calculator? That is definitely next up (I am so bad at this -- last night I had to calculate for the Xth time a new stop bath).
Best,
Todd
