The L-test compares a reflection with a partner a fixed step away, and the step it used preserves the parity class of a half-integer pseudo-translation - so a pseudo-body-centring was invisible to it by luck rather than by design. A translation of one third is not so lucky: it puts the two members of a pair in different modulation classes, inflates the statistic past the bound that is read as evidence AGAINST twinning, and the twin call is lost silently on a crystal that has one. Choose the partners so every pair stays inside one modulation class, which is what the half-integer case was already getting by accident. The obvious alternative - lengthening the step until it clears a third as well - was measured and rejected: it puts the statistic past that bound on more than two thirds of the corpus against a seventh today. Measured over a hundred and thirty-seven crystals: a hundred and twenty-nine unchanged, seven repaired, and exactly one verdict moves - a crystal whose twinning was being denied by its own pseudo-translation. On a synthetic perfect twin carrying a one-third translation, both indicators are destroyed before the change and both return after it. Nothing branches on this verdict, so no merged intensity moves; the whole effect is what the report says about the crystal.
