Your bettor profile

The Analyst who thinks he's god

You have an edge. Your spreadsheet says so.

You don't bet on intuition, of course not. You have models, market reads, a spreadsheet that proves the house is wrong and you're not. And maybe you really are smarter than average. The problem isn't your analysis: it's your yield. You've spent months convinced you have an edge and months in the red, and instead of reviewing the model, you review your luck. Variance, you tell yourself. The Analyst who thinks he's god confuses effort with results: because he worked hard on the bet, he assumes it's a good one. But the market owes you nothing for your hours of Excel. Having an edge isn't believing you have one: it's being able to prove it over a large sample. And yours, be honest, doesn't prove it yet.

The number you should know

Telling a real 2% edge apart from pure chance takes hundreds of bets: over 50 plays, even a losing bettor can be in the green through pure variance.

Three concrete tips

  1. 01Work out your real yield over at least 200 bets: below that it's not edge, it's noise.
  2. 02How hard you work a bet says nothing about whether it's profitable: they're different things.
  3. 03Use an honest value detector and bet a fraction by Kelly: if your edge is real, it survives caution.
