Sorry not to have replied sooner. I've been away on holiday, out of
email range, and have only just returned.

Musicality was not a primary goal for this: rather it was complexity
and variety of methods, with a relatively simple calling for a cyclic
seven part. Where I was able, I tried to include some relatively long
courses without calls.

For the twenty-three method version the counts are

7    2345xxxx, etc.
3    5432xxxx, etc.
6    xxxx2345, etc.
12  xxxx5432, etc.

While exactly which wiggle around a little, the other arrangements
generally have fewer total such rollups, roughly monotonically
worsening as the number of methods decreases.

If difficult, cyclic compositions of spliced appeal, you might also
want to have a look at


While perhaps a little silly, it is, as far as I know, the first *truly*
each lead different peal of spliced major. Again, though, musicality
wasn't a primary goal.
