[r-t] Proportion of Surprise Methods

The criteria for deciding whether a method is to be regarded as Surprise or
Treble Bob were laid out in 1906. In the report on Classification, available
at methods.org.uk, Surprise methods are those which have internal places at
all cross sections, whilst Treble Bob have no internal places. The
intermediate case - some but not all - is well worth reading for yourselves.
As I have mentioned before, it does not help that the lowest stage, Minor,
is atypical of stages as a whole; in this case since all such internal
places are adjacent (to the treble). I have posited elsewhere as to whether
the 3-4 places in Kent TB Minor are 'counted' from the front or the back.
Either is valid - rather like Schrodinger's cat, the theorist cannot be sure
until the experimenter decides. In the case of Kent, they look as if they
are 'counted' from the front. (We think of it differently these days).
It is worth remembering that, even before 1906, some Surprise Major methods
without all adjacent places being made had been rung: Yorkshire (1903),
Oxford (1897) and London (1835).
PJE does have a valid point when thought about at leisure not usually
associated with these e-lists. I cannot see whether it is any more correct
than the current situation, however. To justify any wholesale renaming, the
Exercise at large would have to be persuaded and I suggest the case would
have to be overwhelming for the effort involved, which I do not see that it
is. Reading the arguments put forward, it seems that is comes down to the
way an individual thinks of a method.
Anyway, wouldn't the answer to the original question - the proportion of
TDMM methods which are Surprise - be better found by counting through the
Collection? (Two, three or four consecutive places at your choice.)
This reminds me of the dicsussion about 9 months ago. That essentially came
down to replacing rules which are 300 years old by those which wrere at
least 340 years old.
PS - I tried Richard's methods in Don's prog. The first was returned as
