In a way I agree, Chio...But, in another, I agree with Shed: I do suspect - though cannot prove (this side of Eternity anyhow) - that, statistically, rather more FI Arctic incursions and 'stellar runs' fail to materialize than do episodes of bog-standard British mush? Then, that's only cos I don't credit FI charts with being all that much more than numerical guesswork, anyway???
Note: the above is not meant as a negative criticism of numerical models per se; just a comment on the present abilities of computers...
