Cheap film developer times : LUSENET : Large format photography : One Thread

I have been using the following formula for some time now for FP4+ - Ilfospeed print developer diluted 1-100 for about 16 minutes (based on standars 125 rating for film speed - however, I was wondering and hoping that some people here knows or preferably has practical knowledge of how long I should use for HP5, and if this formula is suitable for T-max 400 and 100. Thanks in advance.
