Although "single" probably was coined from "single change" in Grandsire
Doubles, it is not a single change in Triples, therefore its use was either
adapted (or always was intended) to refer to a swap of a single pair of
bells. Hence intuitively double means two pairs swapped and triple, three
pairs swapped. 

Defining a bob and single using nature in the way I suggested broadens their
definition, allowing any type of call to be classed simply as either a bob
or a single. Where multiple calls are used in a composition, the
introduction of other names is needed to distinguish the types, such as: big
bob, eighths place bob, double, bingle etc.
