Can won-lost-tied percentages be used to predict future game outcomes or team performance across multiple seasons?

Based on the search results, won-lost-tied percentages can be a useful indicator of a team’s performance, but their predictive value for future game outcomes or team performance across multiple seasons is limited.

Consistency and Recent Performance: The search results highlight the importance of consistency and recent performance in predicting future outcomes. Teams that have consistently won or lost during a season may be more likely to continue this trend in future games. Additionally, recent results can indicate heightened motivation and confidence (if winning) or decreased morale (if losing).

Pythagorean Expectation: The Pythagorean expectation formula, which adjusts for strength of schedule, has been shown to predict future actual team winning percentage better than actual winning percentage and first-order winning percentage. This suggests that won-lost-tied percentages can be a useful input in more advanced predictive models.

Limitations: However, won-lost-tied percentages alone are not sufficient to accurately predict future game outcomes or team performance across multiple seasons. Other factors, such as:

• Team adjustments (e.g., new coaches, player injuries/retirements)
• Schedule changes (e.g., tougher or easier opponents)
• Intangibles (e.g., team morale, coaching adjustments)

can significantly impact a team’s performance and make won-lost-tied percentages less reliable as a predictive tool.

Conclusion: While won-lost-tied percentages can provide some insight into a team’s performance, they should be considered as one of many factors in a comprehensive predictive model. Their predictive value is strongest when used in conjunction with other metrics and adjusted for various team and schedule factors.
