Surely if it meant only places in 1-4; 3-6; 5-8 etc then we would need
yet another classification, However according to
(a truly valuable asset to the web)
when treble hunts up through 2-3, 4ths is made, likewise when through
4-5 place = 6ths; through 6-7;  8ths, through 8-9 ; 10ths.
Clearly by the above definition, Yorkshire is a Surprise method
Similarly :
treble through 2-3 pl = 4ths
treble through 4-5 pl = 3rds
treble through 6-7 pl = 5ths
Therefore, even though it used to be called 'London Marvel'  it is
actually London Surprise
However, surely the formula breaks down on the higher numbers in that
say on 12 bells you could have intersections:
1sts when hunting through 2-3 but then say 1-8 when hunting through
4-5 yet still be 'Surprise'
Hope this helps ;-)
