From what I saw, the conclusion was already drawn before the "test" was performed. ("It's already drizzling. Let's see how they're doing on the beading test..." and both tents were beading nicely - so he began attacking the Tarptent on other grounds, like two guys can't play cards in it.) There was some definite ax-grinding going on there.

It appears the "tester" was mostly interested in proving that his choice (the Eureka) was the absolute best, and The Rest of You Are Doing It Wrong And You Need to Admit I'm Right And Do It Like Me. (Franco - I didn't think either tent was particularly well-pitched.)
