Why CLV Matters
Closing Line Value is considered the gold standard for measuring betting skill. If you consistently get better odds than the closing line, you have a mathematical edge, regardless of short-term results.
How to Calculate CLV
CLV = (Your Odds - Closing Odds) / Closing Odds × 100
Example: You bet at +110, the line closes at +100. CLV = (2.10 - 2.00) / 2.00 × 100 = 5% CLV
Why Sharp Books Matter
CLV is most meaningful when measured against sharp bookmakers (Pinnacle, Circa) because their closing lines are the most efficient representation of true probability.
