Milo,
Both fair points, although I don't interpret
they had better 'up their game'
as simply an observation that the RAF weren't there. I guess the poster has an opportunity to clarify his point.
Wrt the posters identity, I was working on the assumption that their first initial is L. He can deny, confirm or otherwise at his leisure (or possibly
her leisure if my assumption is wrong) should they choose to post again and expand their observation.
Yours,
Sun.
