Ah Herman:
think this conclusively shows that it's actually very straightforward to draw detailed contour plots (and that 1970s style arguments about computing power are a bit old hat).
If only the Met Office knew that all they had to do to deflect criticism was to to pretty up their charts and make them look more detailed......regardless of accuracy, and regardless of the ICAO/WMO/CAA stipulations of what they, as a VAAC, have to produce.
As an aside the Norwegian Met Service has nowhere near the computational power of the Met Office, so just because they have spangly charts doesn't mean they're better, though if that's all it takes to placate you, then I do worry.
