You don't understand how WAAS works.

The corrections are to grid points based on observables from multiple
reference stations.

The corrections are based on data from only 29 stations, but they are
extrapolated to an entire continent. This inevitably increases
inaccuracies. It's as simple as that.

You stated:

" The further away you are from the surveyed reference
position used to generate the corrections, the more likely it is that
your position will be incorrect."

Until you recognize that your above claim is patently false, your
replies are of little value.

It's as simple as that.

But I don't expect you to given what I've read in other threads you've
'participated in'...
