Frequently Asked Questions

How many MLB ATS betting systems are tracked?▾

Which MLB ATS system has the highest ROI?▾

"Underdogs in Mid-Total H2H Games" currently leads all tracked MLB ATS systems at +48.48% ROI on a 98-28 record. ROI reflects performance against the closing line at $100 flat stakes — not a back-tested figure.

How do MLB ATS 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 ATS 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.
