To tell the truth I am bit lost here.
Reading all this.
All I can say is that I use the 0.1 speed point as my first reference. I plot my curves to see how the shape is. This is important for me. When I use my adopted method (a bit of this a bit of that) I can usually make my print at about Grade 2 (to simplify this using Grades), I increase the development times slightly because I like to use unsharp masks and the funny thing is I land at a contrast of about 0.62 which is what most published time use as a standard. However my actuall development times are always less than published and I always have to overexpose.
I am always amazed and wondering when people say they use box speed. It doesn't make sense to me.
