This analysis is interesting and thought provoking.
Thanks to all those calculator gurus. The following is not intended to denigrate your excellent work. The analysis is valid.
However, a league table is not absolute, so a top team, when we play them may end up as a mid table by the end of the season. Some of the conclusions identified in posts above are flawed, as they are based on final league positions.
Someone with too much time on their hands would need to map our game results with the league position of the opponent's at the time of the match for an accurate analysis.
Although, we all recognise, and the analysis done in other posts, supports the fact that we did not do well against teams that parked the bus and competed with teams that tried to match us.
eg the Carlisle game of 2 halves
Then you also have the outliers such as: Humphreys missing 2 penalties,
Players getting red cards and affecting results
Easing off after getting back the -8 points
Rather more outliers than are acceptable, I think. "Football, bloody hell", to quote someone famous.
