Interface Departure

Whether the tolerance the derivation states at present still admits it. Absent where none was given to compare against.

This sees one direction only. A departure is by definition a reading the calculated window rejects, so this says which of those the stated window joined and which would therefore be taken apart. It cannot show the converse, a reading the stated window rejects and the calculated one would join, because such a reading is no departure and never reaches this list. changesBetween reports both, and the ones it adds are the silent ones.

How far the copies under test put it from where the rest put it.

Which end put the reading outside the window. At least one is true, and a reading far out at both is true twice.

It is worth seeing apart. The onset, with the kind, decides whether two copies read one command; the end decides whether that command was lengthened or shortened. A separation the end alone makes is as often a punch measured badly as a punch genuinely prolonged, and an editor cannot tell the two apart without being told which test did it.

The symbol read.

That displacement in units of the scatter, at either end.
