I _think_ that table is measured in groups of chargers.

If so, comparing the brands is a bit moot since most non-Tesla normally has at least 4 (and normally much more) charging bays where as many other DC fast charging places normally have less than 4 (often 2).

No? I guess I'm not sure what you're looking at, it's all explicitly called out. First column is level 2 locations, second column is level 2 connections (aka: charging bays). Column 3 is DC locations, column 4 is DC connections per location. Column 5 they conveniently do the math of average connections per location.
