A year or two ago, the Central Council decisions (often known as "rules") were amended to allow the naming of methods that are false in the plain course. The issue came up in relation to methods used in peals of cyclic spliced maximus, where the methods were designed to produce musical changes in a cyclic composition, with no intention of ever ringing a plain course. The argument for changing the decisions was that we should only be interested in the truth of a performance that is actually rung, not the truth of a course of an individual method.
This week my eye was caught by a handbell quarter that took advantage of the new decisions to name "Plain Treble Bob Minor". It's Plain Bob Minor but with treble bob hunting instead of plain hunting. A plain course is false, but the standard calling gives a 1440 in which every row occurs twice. It could be an interesting way of practising treble bob hunting, so I will keep it in mind next time we have learners at that stage.
The method is not only false in the plain course, it's false within a lead. The only way to name the major version would be to ring a double extent!
