Thank you polyglot.
So, if I am producing test strips under any circumstances (not just Thornton's methodology), if I am switching the light-source on and off for each exposure-step, then I must do the same when making a full print; or, if I leave the light-source on but use a mask to cover (or uncover) steps then I must expose a full print for the total time of my chosen step. Correct?
The corollary being that mixing the two methods will lead to discrepancies.
