Its an adapted graph I used last season. I think some neep on the hat had tried to state that things were improving by the end of the season or were not as bad as the start of the season. The graph is quite simple, based on a tally system to try and show form. A win sees a point added to the tally, a loss a point deducted from the tally and a draw the tally stays the same. This is last years graph:
The shocking fact illustrated is that we only won 3 of our last 20 games last season, (the graph does not include the St Mirren win on the last day).
I hope you are better at reading your patients charts
