Actually I think the only block constructions are ones which don't meet 
this: "No bell shall lead or lie continuously for the entire plain course 
of the method."

So consider this plain course:
X58X14.58X58.36.14X14.58X14X18X14X58.14X14.36.58X58.14X58X12X58X14.58X58.36.14X14.58X14X18X14X58.14X14.36.58X58.14X58X12

It is a round block 64 changes long, rather false, but is divisible into 
two parts giving this lead:
X58X14.58X58.36.14X14.58X14X18X14X58.14X14.36.58X58.14X58X12

My reading of the decisions says:
It has 8 hunt bells.
It is a differential hunter.
The primary hunt is the treble which is treble dodging.
It is a surprise method.

Perhaps 3,4,5 etc. lead round blocks of this then give different methods 
each to be named differently even though the basic lead is the same.

Do we yet have a program for automatically fully classifying blocks of 
changes? Resolving name conflicts could be complex as it involves method 
extension and other method names (for reverse, double, single). I know 
many things could change over the next year but seeing the effect of 
changes will be important.
