I don't know what agitation regime you're using, but here's what I've been doing for 11x17.
4 liters of solution, I have been using D76, 1:3 and 1:5, but have run out of that, and will be trying HC 110 5 litres, 1:100 next. No pre-soak, agitation for the first 20 seconds, then stand for the remainder of the first three minutes. Gently lift film from bottom of the tray (smooth bottomed) and turn over and repeat. This is for a process time of 12 minutes, so I was flipping the film over three times.
For the next batch, HC110, I plan on only having to flip once, but I need to determine the overall time first, then flip on the halfway point.
Do you think that the extra density around the edges might be to do with increased development? This semi-stand method might help with that, since the film is lying on the bottom of the tray for long periods, minimizing the effect of fresh developer ingress to the underside.
I should be doing another batch soon, need to repurpose some space. (Tidy up)
