It is not just the PHB recommendation, there are many very sensible factors that play into the cards of a 4 Player Party. It has a lot to do with campaign building, story telling and encounter design.
If you need help understanding it just ask, I'll be happy to.

Pff. Please.
But again: try to calm down a little bit, or at least have a clue about what you are talking about. Right now you just come off as a child throwing a tantrum, because it does not get sweets (-> more than 4 player party).
Well, it could be worse: imagine coming off as a patronizing prick that doesn't have the faintest clue of what he's blabbing about.
