Where are the most knowledgeable guides?

I recently discovered an interesting study and wanted to know if anyone else has encountered it. 😊
The research analyzed 20K angler reviews and focuses on the expertise of fishing captains.

​​​For example, ranks #59/74 based on mentions of knowledge in anglers' reviews:

In Erie, PA, anglers mention the captains' knowledge 21% less frequently than the national average. However, professionalism is mentioned 23% more often, highlighting captains' experience. That said, opinions on educational skills are mixed, as they are mentioned 45% less than the average.
