MBD: "Basically, any good property of a method or composition should be 
invariant under rotation. I could mention changes of method. ;-)"

I have no problem with the changes of method being invariant under rotation,
but I fail to see why it's a "good property". Except perhaps to
differentiate peals that are Stedman in the first half and Grandsire in the
second from peals that mix them up a lots more.
