Oh come on. As DD says, that's still a useless capacity, and do remember Tom is doing this on the hoof, I'm sure if he knew every spec that AFC want included/excluded, and had time to do this fully as a professional job and not knocking it up quickly, it would be even more accurate.
Rather than knocking AFC's figure, he's rather proved the point that they are being honest about how much a redevelpoed Pittodrie would hold.
Let it go, wherever the Dons end up, it's not going to be there.
