Pyrocat HD dilution - development time relation

[Anon Ymous]

Hello all...

There are several common Pyrocat HD dilutions, such as 2:2:100, 1:1:100, 1:1:150 etc. I'm only interested in those where there are equal volumes of the A and B parts. Assuming that I know the development time for a specific film - dilution, is there a rule of thumb that will give me a development time for another dilution?

Thanks in advance.

I process the same films 15min 20ºC in an inversion tank at 1+1 to 100 and 9 minutes in a dish at 2+2 to 100. There's not really a rule of thumb as it varies with developer types.

Oh yes, I know that different developers behave differently when diluted, I was asking specifically about Pyrocat HD. Anyway, thanks for the tip.
