I've tried saying this in the past. His statistics are not a like-for-
like comparison with any forecasting house statistics. Find me a
forecasting centre that forecasts when it feels like and maybe then a
comparison is worthwhile !! Dressing up a small proportion of
forecasting days when the wind's in the right direction as having 70+%
accuracy is entirely misleading, as far as I'm concerned - heck maybe
I'm wrong.

Nothing that Dawlish hasn't always been open about of course.
What would be interesting though is not so much the % accuracy but
the % number of days the forecast is attempted. And that can't
be very many, perhaps once every 1-2 months by my reckoning.
Keep maintaining that accuracy rate, whilst increasing the frequency
of forecasts would be more impressive.

If you don't like calling it a forecast then it's an indication of
inter-model correlation at 10 days. Interesting as an excercise
but a world away from being a 'real' forecaster who has to take
a judgment call on the tricky stuff as well. But I'm sure Dawlish
has always acknowledged that.
