Ties

Leagues treat ties differently: the NFL counts a tie as half a win, while others ignore them. Choose the option that matches your league's standings.

Reading .610

A .610 record over 82 games is a 50-win season in the NBA, which usually earns a playoff place. Percentages are written to three decimals in baseball and basketball standings. At least one game is required.

Background: fitness estimates

Fitness formulas are estimates whose accuracy depends on the input. One-rep-max formulas such as Epley and Brzycki give different answers, and predictions from hard sets of a few repetitions are better than from sets of ten or more. Age-based maximum heart rate formulas can be off by 10 to 30 beats a minute for an individual; Tanaka's 208 − 0.7 × age is generally preferred to 220 − age but is still an estimate.

Pace models built from a race result assume a maximal effort and work best for distances from about 5 km to the marathon. Use the output as a guide, not a prescription.

Assumptions and limitations

  • At least one game
  • Not a diagnosis

Estimates from formulas describe averages. They are not a training or medical prescription; check with a qualified professional before changing your exercise or diet.

If a required value is empty, not a number, or outside its allowed range, the form marks that field with a message and shows no result instead of a misleading number. The automated checks deliberately try invalid entries for wins to confirm this.
