How is this calculated?

A team is counted as still in it when at least one set of results for the matches left would put it there, taking into account that its rivals also play each other. It is counted as sure only when no set of results can take it away. Teams level on points are treated cautiously while matches remain: level is enough to stay in, never enough to be sure, because goal difference and the other tie-breaks are only applied once the season is over. Points deductions are included as published in the league table.

Roma led Serie A after matchday 4 of 2026-27.

They were level on 12 points with Inter. Nothing was decided mathematically on this matchday.
