I don't think it is easy to find out if the cost for the high level is commnig back to the team. Even if you compore 2 very similar teams in the same division, they would need to start off with the same season ticketholders, and win and loose on the same days against the same ranked teams and so on and on.
It's prety impossibly to compare like this, and only a good compare could result in a good calcualtion of this stuff.
Nobody can predict what would have happened when they would have a PR10 instead of 1, or the other way around.
We all know what the PR man is supposed to do, and we may asume he does that, but we do not know to what extend he does that...
They are not your friends; they dispise you. I am the only one you can count on. Trust me.
