[r-t] Unprinciple extent!

[Graham John]

Ander gave:

> lead=
> &-4-1.4.3.4-4-, 23,
> &-4-1.4.3.4-4-, 23,
> &-4-1.4.3.4-4-, 234,
> &-4-1.4.3.4-4-, 234
> (lh 231564)
> 
> bob=23 at lead end
> 720: 3 Homes

Nice example to prove the concept, Ander.

Other than the theoretical interest, I'm not convinced that unprinciples
will offer much from a practical point of view. For example, a method should
really be defined as the shortest/simplest place notation that helps ringers
learn what is required. In this case, describing this as the underlying
principle &-4-1.4.3.4-4- with a division end of either 12, 34, or 36 means
only a quarter of the learning is necessary.
