When the Industry is high you will get alot of 7.0 and as Michigan Mike said you might even hit 8. I dont think in any of my games I have ever hit 8 however. I usually get somewhere between 6.30 and 7 when using WWE.
Ratings also vary depending on what TV Station you are on.
I had my weekly on NBC, but my shows were also averaging around a 90 overall every week. I literally had no fluff on my roster. All of my guys were bulked up in development and then gotten over through good booking or a manager. For right now I have Jericho vs Styles fighting for the world title. That's like an instant 95% match right there.
