I don't think Everton's home record can really get that much worse when they move into their new stadium next season though.
Exactly how they are bad changes, though - when you take the Emirates Stadium (Arsenal's home ground in London) tour, for instance, they actually include some details about how the table in the middle of the away dressing room is designed to be uncomfortably high in a way that keeps team members from making eye contact, which is something that the stadium designers thought would be annoying. At one point, at least, the self-guided tour narration actually included a comment that Pep Guardiola hated the layout.
I still don't think PHP is a good idea for a greenfield project or anything, but they have done a good job of hiding all the footguns.
