Base fog is never good, but really it seems like the less contrast possible with a developer, the better for what I'm using it for. I did fix my film fogging problems that caused what looked like base fog/stain. I also had to change agitation to be very vigorous and every 30s. Otherwise I was getting uneven base stain between the edges and center of the film as well as exaggerated edge effects. The base stain is definitely still prevalent (though significantly improved) when using longer development times. the time for minimal fog but max speed of ~6 ISO is around 7min and agitation every 30s at 1:1:100. Speed seems the same with 1:2:100 but much higher contrast with this film. I actually found I get a bit better density by using a mix of 6:6:500 without adding too much contrast.
So less of part B seems to be safe to reduce the developer activity and contrast, but doesn't seem to affect time or development speed. It only seems to affect contrast and how dense the highlights get. Using the 6:6:500 dilution seems to work really well for great exposure latitude due to the super low contrast. It especially gives ridiculously wide over exposure latitude. I tested this by going around 10+ stops of over exposure and still got a great looking picture with minimal highlight blocking. With PMK if using extreme over exposure, the color of the negative with vary from orange to green to blue and can be processed to give an interested split toned look when scanned.
