 The order of teams is alphabetically and the same as in [[predictions_pl|predictions for 2019/20]]. Squares around the team symbols mark //home games// and  diamonds //away games//, respectively. Gray symbols belong to the first half of the season, black symbols for the second part.  The order of teams is alphabetically and the same as in [[predictions_pl|predictions for 2019/20]].

 is shown in blue. A high efficiency corresponds to a slope $\alpha>​1$,​ $\alpha<​1$ to a low efficiency. The axis section $g_0$ indicates how many goals a team scores in games with equal scoring chances ($xG_{G}\simeq 0$). The larger the axis segment, the more often the team has won, conversely a large negative axis segment means that tight  games are more often lost. This number is an indication of luck or skill. is shown in blue. A high efficiency corresponds to a slope $\alpha>​1$,​ $\alpha<​1$ to a low efficiency.
