[r-t] Method extension

[Rebecca Cox]

Aren't most of the problem with method extension caused because we are 
looking at the problem from the wrong perspective. Extension looks at 
the problem from the lowest stage upwards, whereas we should be looking 
at all stages together and asking whether the methods at different 
stages form a family group. To be in a family there simply needs to be 
at least three methods at different stages with an equivalent 
relationship between them. The method at the lowest stage may not show 
all the features of the other members of the family because in a 
decreasing series zero is the next number below 1 and, of course 
methods, may be in more than one family.

Taking this approach, Bristol S Major, Royal and Maximus are clearly in 
one family
but so are Bristol S Major, Littleport Little S Royal and Maximus
Also New Durham Major is in the same family as Durham S Major
