I don't like this definition of a lead.

Consider the method &34-34.1-2-1.34-34.1,1 -- from the place 
notation this looks like a perfectly good treble bob minor 
method, and it would easy enough to imagine this appearing 
in a peal spliced treble dodging minor and no-one thinking 
twice about it.

Looking more carefully, it has the lead-head 145236 which 
means (under the current rules) that it is actually a 
differential treble bob method.  I'm not keen on this 
distinction between differential and non-differential 
methods as it doesn't reflect the reality of how spliced 
minor is actually rung.

But using Mark's definition of a lead, it is worse than that 
because the 24-change fragment that forms the obvious lead 
is in fact two identical parts.  Under Mark's rules, this 
means the lead is 12 changes long, and the method is a 
differential, not even a differential hunter.  This means 
that, for example, it can't be included in a peal of spliced 
treble dodging minor.

So, for the same reason that I support getting rid of the 
differential hunters as a separate type of method and making 
them fully fledged 'hunters' (nasty word), I don't want to 
see this definition of 'lead'.
