6 older matches left the 12-month period: 5 won and 1 lost. The rating is then recalculated across the full network, so the monthly change is not a sum of separate deductions.

This is a current what-if estimate: roughly how much the current rating changes when this match is omitted. These values cannot be added and therefore do not together explain the monthly change.
