[r-t] Elegant unrung methods

[Philip Earis]

It's been a bit quiet here recently, so I've got a question which is partly 
historical in nature.

Has the very neat doubles method (&5.1.2.1.2, 1) been documented anywhere 
previously? This is a very simple way of generating the extent (eg 3*ppbb, 
b=145)

Alternatively its reverse: (&5.4.5.1.5, 4).

They are also iterative ways of getting the extent - in some ways a logical 
"extension" of firstly plain hunt on three and then Reverse Court (or Single 
Court) Minimus. It seems the kind of thing Stedman would have mentioned, but 
I couldn't see anything in a (very) quick scan of Tintinnalogia 
(http://www.gutenberg.org/files/18567/18567-h/18567-h.htm). Instead, he 
seems a lot more preoccupied with various somewhat contrived ways of getting 
an extent by using variations on plain changes.

So have people rung (or discussed) these before? It seems hard to believe 
otherwise. They look like the kind of thing some people might use as a 
"training tool".

Of course, that these methods are not allowed by the current CC Decisions 
for having too many consecutive blows is a good example of how wrong and 
prescriptive those "decisions" are.
