Finding zero such players defies probability.\n\n2. **Contradicts sports psychology**: Elite competitors typically include players who perform better under adversity, feed off hostile crowds, or are simply venue-agnostic. A 100% directional effect is unprecedented.\n\n3. **Magnitude is extreme**: A 43-point average swing is not a subtle edge — it represents the difference between a dominant player and a struggling one.\n\n4. **Perfect consistency**: Even at the extremes, no player bucks the trend. The distribution shows variation in *how much* home helps, but never in *whether* it helps.\n\n### Implications\n\nThis finding suggests one of three scenarios:\n\n- **Systematic match assignment bias**: Stronger players may be disproportionately assigned home matches, creating a confounding variable where \"home\" correlates with skill rather than venue\n- **Extreme environmental factors**: The home venue may confer advantages (equipment familiarity, table characteristics, lighting, etc.) that universally outweigh individual player psychology\n- **Data encoding artifact**: The `HomeWinner` field (which is binary 0/1 and perfectly balanced at 50.34%/49.66% across all matches) may encode something other than physical venue\n\nThe fact that overall match outcomes are perfectly balanced (home wins 50.34% of all matches) while *individual* players show massive home advantages points toward the first explanation: match assignments likely aren't random, and home/away designation may proxy for seeding or ranking rather than physical location."
