BEHIND THE DATA
Behind the Data
See how each finding is calculated, where the data comes from, and what it can tell you.
Read percentages with their sample sizes and comparison baseline. Muted differences have not cleared the stated uncertainty threshold. Each method explains its evaluation and limitations.
Data sources and season coverageWhat the tests did not establish
These findings have limits too. A test that finds no clear effect does not prove the effect is exactly zero.
Season win totals Favorable schedules did not consistently predict beating preseason win-total lines in the archived sample.Time zones Travel direction on short rest added no predictive value after accounting for team strength and other schedule factors.Referee folklore The tested pair records and home-favoring patterns did not exceed their chance comparisons. Foul volume did differ across officials' games.Playoff winner selection Winner accuracy was close to always picking the home-court team. Probability estimates improved.
