[r-t] round trip terminology

[Philip Earis]

Richard on "round trips":
"I'm not sure how useful a measure it is.  Consider Superlative, say.  It only has one round trip from front to back, but quite a bit of movement between lead and 6ths, and 3rds and 8ths"

Agreed. Consider Cambridge Blue Delight Major (&x36x1x5x36x4x1x36x1,18). This is structurally very similar to Superlative, and yet instead of Superlative's 1 trip Double Cambridge has 7 "round trips" and very fluid hunting. 

Metrics which measure blue line artefacts (ie secondary effects) rather than underlying structure can seem a bit contrived.

However, that said, an interesting alternative measure of fluidity is whether all place bells ring in all 8 places in a lead. This has been discussed on here before, I think. London major was given as a rare example for surprise major methods (though it's a bit of a dubious example as with the formal definition of lead, from leadhead to leadend, 7ths place bell doesn't ever ring in 8ths place)

I'm sure Richard can give a list of such major methods which meet this maximally-fluid criterion.
