(rab) No. I will have no truck with such arbitrary adjustments in my sophisticated numerical analyses :-). You are right, of course, provided you were born in Britain, or possibly Spain or some West African countries.
(Bigsmith) And so are you. (6 pm, they tell me).

[uohrixg yzrqmefdx] That, good sir, was jolly close, as I believe even Rosie would acknowledge. I do think though that you have missed by a bit. Rosie does not live 'south of the border' and nor does he live so far west of the meridian.
I would give you 'bvyk anq.s and ityksr+polar co-ordinates' when related to the orbit of Triton as seen from Earth.

[Rosie] 6 pm aye? Then by applying the Euclidian theory of longitudinal drift to a trans-Mercator projection I determine that that would have been in Crowborough, Sussex.

(Bigsmith) Correct yet again. Amazing. Would have been Purley (nudge, nudge) but for the war. The OS Grid is a Transverse Mercator projection BTW. Very gudermannian. (Dujon) 0° 03' 36.8" W. Can't be too accurate; don't want to go in the wrong house.

[Rosie] Bugger, I thought I'd made it up! I remember we have discussed things map-wise before. I do enjoy a good OS map so it must have been subconcious. WildpantsMC may be long gone but the player profiles page is still on-line and easy to search.

That's how I know about your London Welsh parents!
