I've checked my records - I haven't really done much with P3200 -- In 2002, I developed a few rolls of 120 in Rodinal 1:50 for 17 minutes 00 seconds; In 2003 - Ilford DDX, 1:4 for 9 minutes 00 seconds; and in 2004, Rodinal 1:25 for 11 minutes 00 seconds - all at 20 degrees Celsius - and all exposed at ISO 3200.

This all was used in terrible "available light" situations - and all was generally "satisfactory" - good enough to print.

Hope this will be of some - minimal - help.
