Alright. My recent testing of HP-5 in the Jobo a the 2:2:100 dilution at 73 degrees and the slow rotation gives me the following times for a target DR of 1.05:
Normal (SBR 7) EI 250 - time 6 minutes
Normal +1 (SBR 6-) EI 250 time 10.5 minutes
Normal +1.5 (SBR ~ 5.5) EI 320 16 minutes
Notice that I don't have any N- times at this dilution. It is just too strong. My guess would be that an N-1 could be achieved at 4 minutes, but I didn't run any times this short. If you are only doing silver, I think I would use the 1:1:100 dilution, unless you are faced with a serious N+ expansion situation. Sandy might have some better information on the proper times for this dilution.
And about the Houston/Galveston area, sure. I have to check with the ruling authorities and so forth, but I would definitely like to get out early before the heat and humidity gets truly murderous. Email me off list and we'll see if we can work it out.
