How do MLB Over/Under systems get graded against the closing line?▾
Every qualifying pick is settled against the sharpest closing price. Closing line value (CLV) measures whether the pick's original number beat the market's final number. Consistent positive CLV over 50+ picks is the single strongest indicator of long-term profitability.
What sample size is meaningful for a MLB Over/Under betting system?▾
15-20 picks is the floor for statistical signal, and 50+ picks is where a real edge typically separates from variance. Short-sample systems can look exceptional or terrible purely by luck — sample size matters more than any one headline number.
