I was once told (by Peter Hawcock) that it was possible to bring round any
touch of Plain Bob minor with just one call. This isn't actually true as
there's at least (maybe just one) case when two calls were needed. (It goes
without saying that it must be true at least for all regular minor methods.)
As Grandsire triples is just Bob minor at the next stage, then the
three-call requirement is not surprising.

Does this generalise to more bells than 7. i.e., given N bells, is the
number of calls required (in a treble dominated method) a simple linear
function of N,. such as N-4?
