Let me restate, then:Wow, talk about statistical manipulation...
There were 4243 respondents. Only 4% of them thought Cook was "overrated".
That bizarre ratio you quoted illustrates the point that Fortune itself makes in the article: he's 3rd on the list of most overrated CEOs and also voted 5th most underrated.
Or, as you would say, 3:5...
Of the 4243 respondents, that called-out a personal opinion of Cook's management style:
183/4243 [overrated] : 72/4243 [underrated]
2.3 : 1 felt Cook overrated
(Off [(182+72)/4243]=6% that voted an opinion)
