Agree the handling of this situation isn't completely clear in today's
Decisions. As MBD points out, the current Decisions define a method by its
plain course, whereas it would be clearer for the plain lead to be the
defining unit of a method.
However, the method collections do effectively define methods in terms of
one plain lead, since this is what is recorded. It's then accepted that
the plain course of a method is the number of plain leads that need to be
rung to bring you back to your starting row.
Simplifying Andrew's example, if a method is defined in the collections as
having place notation xx, the plain course of this method would also be xx,
i.e. it would be a method with one lead in its plain course. (These today
are considered non-method blocks, though, as Don has pointed out
previously, this relies on the "divisible into equal parts" (plural)
language, which isn't entirely unambiguous.)
If you wanted a method to have a plain course xxxx, you would record xxxx
in the collections as the plain lead, and it would also be a method with a
one-lead plain course. In the current structure of the collections, there
isn't a way to distinguish a method with plain lead xx and plain course xx
from a method with plain lead xx and plain course xxxx, and it doesn't seem
necessary or helpful to be able to support the latter construction.
Actually I think the only block constructions are ones which don't meet

Agree, this is the other remaining construction (a bell leading or lying
for the full plain lead) that gives a non-method block.
