Brian's paper (slightly modified to use standard place-notation) says:
Almost no methods selected for recording were in the 1991 Central Council
Collection, though a few came very near to Bristol Surprise Maximus. There
tended to be multiple results with a simple juggling of places such as
78.56 and 5678x and 56.78 and x5678 - all methods with nearly-equal values
Swi is swings of the blue line in the plain course - front to back to
With Sweetie Delight then there are several trivial variations.
which according to my count has more runs, but my program counts them
differently from Brian's.
I count 321456789E0T as 3 4-runs, 2 5-runs and 1 6-run. Brian counts it as
1 6-run, worth 6 points.
There is a conversion process between the run counts.
E.g. each 12-run has 2 11-runs.
Nnn = number of nn-runs
Snn - number of strict nn-runs (not part of a bigger run)
S12 = N12
S11 = N11-2*S12
S10 = N10-3*S12-2*S11
S9 = N9-4*S12-3*S11-2*S10
I haven't counted the closeness coefficient for this variation. Perhaps
his program rejected this for some reason - the closeness might be worse.
Maybe the closeness coefficient should include the treble to be more
Graham John mentions 'This has 120 changes of 4-bell coursing, compared to
112 in Snow Tiger.'
Is 4-bell coursing the number of rows with 4 coursing bells in the same
positions as in a row of a plain hunt or is there another definition?
