Frequently asked questions
Every win by your team and every loss by the closest rival cuts it by one. A day when both happen drops it by two, which is why it can fall fast in September.
The team has clinched: even if the rival wins out and your team loses out, the rival cannot finish ahead. Negative values just mean the clinch happened games ago.
The mirror image: a team's elimination (tragic) number counts its own losses plus the rival's wins before it is mathematically eliminated from the race.
Whichever race you are tracking. Compute it separately against the closest team in each race — the smaller number is the one that clinches first.
If the rival owns the head-to-head tiebreaker, your team may need one extra game to clinch outright rather than tie. This calculator shows the standard formula without tiebreaker adjustments.
