Hiding in Plain Sight Post No. 13
Using the highlighted row in this chart and working off the assumption that N = 7 stops, N+1 = 6 stops and N-1 = 8 stops of subject that has to fit on the No. 2 paper.
AND, assuming I'm correct with my flare-chart adjustment...
N time should fall around 6 minutes.
N+1 around 9 1/2 minutes and
N-1 around 4 1/2 minutes.
I would not recommend development times of 4 1/2 minutes because it could lead to uneven processing.
In the case of N-1 I would suggest a change to your developer. I think Michael R 1974 can give you some good ideas there, as it's one of his specialties...
