So we seem set on 'the throw to the odd' for sorting a MONTHLY mean - but
what about seasonal and YEARLY means?

For a Yearly mean would you use
A - the mean min + mean max divide by 2 and apply the throw to the odd rule,
or B - the sum of the 12 monthly means divide by 12 and then apply the throw
to the odd?

A is correct, provided the mean min and mean max are the means of 365 (or 366)
daily figures.

B is incorrect as the individul months are of differing lengths.

In practice, I suspect that in most cases you would end up with the same answer
using either method.
