Agreed. Tried to cover that in the disclaimer:
"Disclaimer: While the data obtained from BeerAdvocate is taken at face value for the purposes of this analysis, one is well within reason to further analyze that source data in terms of the completeness of the listed beer styles, definitions of those styles, appropriate beer style grouping for the given commercial examples, verification of actual breweries in production, etc. In addition, considering that much of the data collected by BeerAdvocate is added by its users, one may further wish to question how that user group may affect the overall data (% of English-speakers, % of American users, etc.).
Also, the methods and parameters of data analysis herein are but one way of looking at the given information. Furthermore, all of the data collected from BeerAdvocate occurred in Feb. 2018, and therefore represents a single time-slice of the beer landscape, which of course is subject to change in the future.
Lastly, interpretation of the data above is up to the individual, for as the old adage goes, there’s more than one way to brew a beer."
