Here are the minimum and maximum points for each team in the October 2020 ranking. FIFA will publish the ranking on October 22nd.
Minimum and maximum points per team are determined with a small piece of software which calculates per match the minimum and maximum possible points for each participating team, given the minimum and maximum starting values of both teams before the match.
Note that only scheduled (and included) matches with both teams known at calculation time are incorporated in this analysis.
