PR/Grid rating: A snapshot correlation

In Response To: PR/Grid rating: A snapshot correlation (Jason Lee)

Agreed. I was keeping an eye on the polynomial as I was going along, and it felt like it was "trying" to be linear - i.e. after each few new datapoints were added, the sign of its second derivitive, indicating the change in the gradient of the polynomial trendline as PR changes, often changed from - to + or vice verse, so the fact that it ended up one way or another (+ or -) is totally inconclusive, so I'll assume the function is linear for now. More data for lower rating ranges might change that, but I doubt it would be significant.
