It’a just going round in circles now.See my post above. Pretty much answers most of it. Dortmund have a dirty great big standing area that has 20k fans in it alone, they are also some of the most vocal supporters in Europe. Put them in ANY stadium in the world even WHAM's and they will still make it seem that they have a great atmosphere.
I have never said it doesn't help make it better on a computer model somewhere but we are talking marginal gains, what you can quantify for sure is how the view is for every supporter, see the difference between stadiums that have overlapping tiers?

You believe overlapping tiers are better, professional stadium architects disagree.
There’s not much more that can be said.
P.a you’ve posted a photo from the top tier of the Millenium stadium which clearly doesn’t overlap the tier below.
