whether you have had a preceeding good run or not is randomised out over the eight seven seasons then
so what you have really is crowds vs previous home result.
I'd not expect to see any great correlation to the previous home game and you've shown that
I'd love to see a chart that showed home crowd versus points average from the preceeding five or six games. My guess is that would show some correlation.
Where'd you get the home crowd numbers from and are they available for every home game back to the first one? I could have a crack at it.
