I know what my job is -- thanks, and therefore how to extrapolate.

Then how come you didn't realise that that is where the error lay?

The errors are in velocity as well as direction, and far above "every
peak."

I thoght you said you knew what you were doing?

Ever heard of bernoulli?

I used winds aloft as one example -- if you're going to assert that
current weather forecasting is 90% exact, I wanna know what service
your using.

And that's forecast -- not observation.

That's forecast.

I use the same as you. Within reason, I'll stand by the 90%. In fact,
that's a conservative estimate. Compared to what forecasting used to be
like, forecasting is uncannily accurate.

We use fido for flight plan sheets. that;s the ones with weather. The
other is the same as you get. I think I've been surprised by weather
once this year.
