-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 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.
