added an indication for OG because I was sick of the xG values being somewhat misleading when they get scored. Fun stat: We've scored 5 and conceded 1 OG this season.
Not OP but maybe I can help? Expected goals and goals for (xGF and GF) and against (xGA and GA) for each fixture and the same fixture last season, alongside the points from the fixture this season, and the difference versus the same fixture last season. Green representing we got more points compared to the same fixture last year. The "matching fixture" is playing the same team (or the equivalent promoted team) at the same venue (i.e. home vs away) rather than a particular match week.
Finally the sum of those differences home and away (i.e. are we getting more or less points from the same games, overall).
The purpose is for a more "like for like" comparison to inform how we are developing, since looking at, say, the overall points total for match week 20 this year versus last year doesn't account for the strength of the opposition. However, you do lose the information about the way we perform at different stages of the season, so it's a tradeoff.
The colours are relative to the corresponding result last season. Less pts than last season's corresponding fixture = red, same number of pts= gray, More pts = green.
We beat Chelsea at home last season, we beat them at home this season. Therefore, grayed out.
