I haved used Dillution B in my Jobo Expert drum - not D.
For B (1:7) here are a few starting times: 70° F - 6.5 minutes = N N+1 is roughly 6.5 minutes X 1.4 N+2 is roughly 1.4 X the time for N+1 N-1 is roughly 6.5 minutes X .7 N-2 is roughly .7 X the time for N-1
For Dillution D (1:9) I would start at 70° F - 7 minutes, = N Once you have established a correct developing time you can apply the formulas for N- and N+ development.
