I agree you do want to aim for around a point a game as the low side of survival and yes you might say we're ahead of target at present, however it is the games we've played that in my opinion see us behind target. After 12 games I think we'll be well below the point per game target, maybe only half way there.
Don't get me wrong I'm not saying it's been a great start it hasn't. It's been an ok-ish start but not the end of the world as the OP seemed to be saying. It's been made more frustrating by the times we've gone ahead then conceded.
We could indeed still be on six points after 12 EPL games but if we beat Palace at home and Burnley away we could be on 12 points. Although I think we'll be on 9 or 10 which will be very close to the bottom of the table.
