[r-t] Compressed Methods

Welcome! Thanks for posting. Sometimes older ideas are indeed ripe for
re-exploring.

Treble dodging methods are divided into sections, ie what happens in each
dodging position before the treble moves on the next dodging position.

Most of the frequently rung treble dodging methods have symmetric
sections, mostly of the form x a x, or b x b.

For example Cambridge-over methods begin x3x, while London-over methods
begin 3x3

Your approach to compressing methods simply omits every alternate piece of
notation.  For right-place methods this is equivalent to removing all the
cross changes, which kind of makes intuitive sense.

What are you trying to achieve overall, though?  Is it to have a
concentrated plain method that shares characteristics with the treble
dodging parent?

If so, you algorithm is a bit questionable for wrong-place symmetric
sections...reducing the 3x3 of London to a mere x is perhaps not the best
way of doing this.

Are you aware of Double Coslany Bob Major?  This was first pealed in 1939,
and is perhaps a more natural compression of Bristol Major:

In Double Coslany, the right-place symmetric sections of Bristol major (eg
x5x) are compressed to their dominant element (x), the wrong-place
symmetric sections (eg 5x5) are compressed to their dominant element (5),
and the notation when the treble moves between dodging positions is
preserved. The result is:

Bristol        x5x4.5x5.36.4x4.5x4x1,8  [m]
Double Coslany x4.5.36.4.5x1, 8  [m]

Double Coslany is a gem of a method.

That said, I do quite like your Half Bristol Bob Major too.  It has a
certain appealing oomph!
