GeoMean measures the geometric mean of the ownership percentages for all players in a lineup. It provides a balanced view of the lineup’s overall popularity while reducing the impact of extreme ownership values. This metric is particularly useful in DFS for evaluating how “chalky” (popular) or “contrarian” (low-owned) a lineup is, relative to the field.
Why It Matters
• High GeoMean of Ownership:
A high GeoMean of Ownership indicates a lineup composed of players who are widely used across the contest. While these lineups may feel safer, they tend to lack uniqueness and are more likely to be duplicated, especially in GPPs (Guaranteed Prize Pool tournaments).
• Low GeoMean of Ownership:
A low GeoMean of Ownership suggests a lineup with lower-owned, more contrarian players. These lineups are less likely to be duplicated and can provide a significant edge in contests, especially when the lower-owned players perform well.
How to Use It
• Cash Games:
A higher GeoMean of Ownership is desirable in cash games, as it aligns with safer, consensus plays. The focus is on maximizing the floor rather than minimizing duplication.
• GPPs:
A lower GeoMean of Ownership helps differentiate your lineup from the field, increasing your leverage. This is critical in tournaments where the goal is to achieve a top-heavy payout.
GeoMean is an essential tool for assessing lineup leverage, helping you find the right balance between popular and contrarian plays based on the contest type and your risk tolerance.
