1. I don't think that Prof Dav claimed to have a statistically valid sampling, nor did he publish his survey results (including margin of error).
He used his sampling as an argument that people are happy with the system, however.
Likewise, I am sure the majority of people who would talk to Prof Dav (especially parents) would say something nice or nothing at all. So he only gets compliments and thus has a false impression on what people think of bo3.2. I also am pretty sure that people commenting on a post titled "...Scrap the Disaster..." are not pre-disposed to be completely unbiased.
In short - just because your own friends, followers, opponents or peers all agree with you on something does not mean it is the view held by everyone involved in the situation. "Everyone" doesn't hate the format, or TCPi would have gotten zero positive feedback. That is a significant flaw in your logic. I'm happy for everyone to have an opinion, but please don't confuse the discussion of "what I think" with "what everyone thinks". Trust me, it won't end well.
Do you think that a majority of players like bo3? Do you like bo3?
