Very cool, thanks for sharing!

What's the threshold function? Do you have graduating `No --> Partially --> Mostly --> Open`?

Also what's the update cadence?

So if it's under 25% of the prior year's crossing it goes to NO, otherwise it's counted as open.

The update cadence kinda sucks because I didn't spring for the $200 a month live ship tracking data, so I'm using https://portwatch.imf.org/pages/cb5856222a5b4105adc6ee7e880a... which lags by 4 days which isn't great for a site like this, but was fine for me on a little side project. Open to other data sources or ideas, of if anyone wants to sponsor an API key (I did reach out to a few vendors already if they would give the project api key in exchange for a link to their site).

The original idea was to track ships and see how many crossed the strait but as mentioned above I didn't find any free sources so I went with what I did.
