what makes a positive-EV tool trustworthy
Positive-EV tools all show the same screen. Four things separate one that can be trusted from one that cannot.
An interval, not a number. Four defensible devig methods disagree by 0.39 points on a real market. A tool that picks one and prints the result to two decimals is presenting an opinion as a measurement.
A fill probability. Expected value you cannot place is worth zero, and it is the largest edges that reject most often.
Calibration against something. A devig method should be chosen by which one predicted closing lines in your markets, not by which one the author preferred — and the new weights should have to beat the old ones on a slice of the record they were not fitted on.
A refusal. Under 30 graded bets, the honest answer is that nothing can be said. A tool that always has a verdict is not measuring anything.
