Or they are ignoring the NOAA warnings and interpolating between stations.
The commercial people do have access to harmonics that the XTIDE-based people (me!) don't have. That's been proven in England and Australia, and I suspect many other places aren't releasing new harmonics but I can't show this. So I don't find it hard to believe that the commercial programs can get current flow models from government agencies after providing some lucre.
Another suspicion I have is that the particular locations that have flows are simpler to model than the San Juan's. I'd have to compare their output for a long period of time with what Mr. Tides produces, and see if there's some correlation. But even after doing that I'd still have reservations about the accuracy of the model I'd come up with, and I don't know what resolution I'd use. The two pictures I've seen on this thread are fairly broad overviews, and I don't know how far down you can go to get detailed flows.
Very interesting thread!
