A pick is a claim about price, not a promise
When a model recommends a side, it is really saying: my estimated probability is higher than the price implies, so this bet has value. The number to look for is the edge — the gap between the model probability and the market implied probability — not just which side it likes.
A pick on a heavy favorite with a razor-thin edge can be worse than a pick on an underdog with a wide edge. Always read the edge against the price, the same way you would evaluate value on any bet you make yourself.
Sample size decides how much to trust a record
A gaudy win rate over a handful of bets means almost nothing. Consider two models. Model A is 60% against the spread over 20 bets. Model B is 55% over 1,000 bets. The uncertainty on a win rate shrinks with the square root of the number of bets, so small samples have enormous error bars.
Using a simple normal approximation and independent bets, an approximate 95% confidence interval is 38.5% to 81.5% for Model A and 51.9% to 58.1% for Model B. The approximation is less reliable for the 20-bet sample. Model B has a narrower interval, but it still crosses the roughly 52.4% break-even rate at standard juice, so this example does not establish a true win rate above break-even.
Trust process signals over raw record
The most reliable thing to check is closing line value. A model that consistently beats the closing line is finding real value even when the scoreboard has not caught up. A model with a great win rate but poor CLV may just be running hot.
Read picks the way you would read a bet of your own: What is the edge? How big is the sample behind this model? Is its CLV positive over time? If the answers hold up, the pick is worth considering — and it is still your bankroll and your call.
