"Both opta analyst and footballxg.com calculate a table based upon expected points. They also offer a prediction for 46 games. However, we haven't played nearly enough games for that prediction to stand up to scrutiny.
The point about xG is that it takes 25-30 data points per game, and not just the goals. It can therefore be useful to judge over ten games and compare vs:
- the competition
- previous seasons
- changes when there's a change in management, or players in/out due to transfers or injury
There will always be outliers, but most clubs will revert to their mean. If a club is outperforming xG then the choice is to ride out their luck, change approach, accept a downturn, or acquire / rehabilitate players.
In our case, Leaburn and Edwards are now available, and we require a win away to Stevenage or Bristol Rovers so as to stay in the frame. Should we win one plus our performances and xG improve then the bookies will perhaps place us back as one of the six favourites for a top six finish?
The point being that the bookies and xG are both independent of any Charlton bias, thus giving us a view which isn't distorted by our own views and emotions when watching the games.
What matters is that Nathan Jones needs to find away to create more, decent chances without compromising the serious progress made in defence. We've made some inroads with set pieces - whether one uses anecdotes or xG our attacking threat is roughly half our competition!"

I am now certain he does believe all the above twaddle, he never posts on Charlton Life but could not help himself once he saw a thread on XG
he really didn’t like that.
