The test set

A table built by hand, frozen, plausible for the comparisons it illustrates

Mind map of chapter 19: lacking collection, the test set is built by hand and frozen. The contrast between the two regimes plays out on the triplet, with arbitrary values — L_d at (80, 35, 50), L_p at (30, 75, 60); closure and recognition are inverted, the translation requirement stays neutral. Ten criteria on [0, 100], all read "more is better". The axioms of Part II fix the direction of the contrasts, the amplitude is a choice — and that is where the fictional character of the table resides.
