Those aren't the numbers I'm afraid.
Two things.
1: Read the whole article. There are actually #'s quoted about how they impact a customer's choice (specifically just one example was consumers were 6 times more likely to purchase an item when only given 6 choices rather than 24, but there's a lot more data there that is referenced as well that supports this)
2: (and more importantly), way to miss the entire point. That article completely affirms the claim that was made. Not having specific D&D numbers in that specific article in no way invalidates the point he/she was making earlier.
