Special thanks to the ZS mailing list for its feedback during the production of this information
Context
The outline below is a document in progress. It is intended
to help analyze film test results. The first step, is always to
get the film speed nailed down for any target development
Calibrating film density to paper exposure range

This page will turn into a complete chapter at some point. This material augments the rest of the chapter. It is not necesary to test you paperr before proceeding before testing film, but there are advantages to doing so. If you do not test paper, just use the commonly recommended densities for your targeted normal density.
The following snippet of a question is from a reader:

Hints and tips to help expedite results
It is easiest to start by testing for N-1 development and film speed than it is to start by testing for Normal development and film speed. After N-1, test for Normal, then N+1, then N+2.
Use one-shot developers. Some developers aren't formally designated asa 1-shot developers but work well that way.
Use fresh chemicals

Miscellaneous notes about film tests
Film tests should be done for each particular
film development that you desire to use. A sort of standard set of film developments is N+2, N+1, N, N-1, N-2. For each of these film developments, a set of tests should be done. The procedure is as follows:
