While I don't necessarily disagree (or agree) with your conclusion
that using "lead" or "row" might have been better, I don't understand
your reasoning at all. If the official "plain course" of Grandsire
Doubles is a specious construction because there is no way to
partition an extent into a set of such courses, doesn't the same
argument apply to Cambridge Major? Indeed, isn't Cambridge even worse
since there is no obvious call that allows construction of some other
building block into which the extent can be partitioned? Do you
believe Cambridge has no plain course?

Also a further observation about Grandsire Doubles: it *is* possible
to construct a multi-extent block out of whole courses. Since I don't
understand your reasoning, I don't know whether or not this is germane
to the argument, but I suspect it might be.
