Over the course of a season….

Does it tend to statistically correlate with the table?

Allowing for a few outliers, you’d expect it to roughly correlate with goals scored and conceded, with the top teams outperforming xGD to some extent due to superior players, and low teams underperforming for the opposite reason?

Isn’t the way to demonstrate that xG is valid to look at a statistical analysis over a long period? Which is presumably how the weighting of a chance is reviewed and refined anyway?
