Why a Winning Bettor Can Lose for Months
You did everything right. Five hundred bets, every one of them +EV, a genuine 3% edge at −110, disciplined quarter-Kelly stakes. There is roughly a 1-in-4 chance you're still down money. Nothing went wrong. That's just what the ride looks like.
The experiment
We ran 20,000 simulated bankrolls through the Actual Odds engine. Identical setup for every one: 3% edge per bet, −110 odds, stakes at ¼ Kelly (0.83% of the live roll). The only difference between them was luck.
The results, in cold blood
After 100 bets: 38% of winning bettors are losing money.
After 500 bets: 25% are still down. The median is +12%, and the unlucky bottom
twentieth are at −16% or worse.
After 2,000 bets: 11% are still underwater, the median is +54% and along the way,
73% of all runs suffered a drawdown of 20% or more. Almost everyone who wins big
first watches a fifth of their roll evaporate at some point.
What this means for you
Judge the process, not the weekend. The only thing you control is whether the number was green when you fired (that's what the devigger is for). Stake small enough to survive the chart. Quarter-Kelly isn't timid, it's the reason the -16% runs come back instead of going bust. And the cure for variance is more bets, never bigger ones. The edge shows up on schedule; the schedule is just longer than your patience.
