An edge isn't a hot streak. It's a measurable, repeatable process that produces positive expected results across hundreds of bets. Here's how to find out if you have one.
A real edge is a measurable, repeatable process that produces positive results across hundreds of bets — not a hot streak. Proving you have one takes three things: a big enough sample (200+ bets), consistent flat stakes, and an honest record of every result.
You're going to have a good month. I'm fine with that. I need you to think it's skill.
Most people who have a good month press harder the next month. Most months regress. They conclude they've "lost their touch" and go on tilt. Or they have another good month and conclude they've figured something out and press even harder. Either way, I get them eventually. The guy who has a good month and quietly asks "is this replicable?" over a larger sample — he's the one I have to think about.
I've had "my system" about eight times. Each one came out of a good 3–4 week run. Each one evaporated by the end of the month.
The longest I've ever tracked systematically is about 180 bets. That was enough to tell me I was a slightly losing bettor at -3.2u. Not catastrophic, but also not a guy with a systematic edge. Before I tracked, I was sure I was profitable. After tracking, I had to face that I wasn't. That actually helped, because it made me take the process seriously for the first time.
Knowing whether you have an edge requires three things: enough bets (200+), consistent stake sizing (flat units), and honest record-keeping (wins and losses both, every one).
With those three inputs, you can calculate your ROI, compare your CLV against closing lines, and begin to identify which situations you're finding value in and which you're not. That last part — attribution — is where real improvement comes from. Not "I'm 57% this month." It's "I'm 61% on NFL home underdogs under 3 and 44% on NBA totals."
The goal isn't to feel confident. It's to have a process you can evaluate honestly and improve incrementally — the difference between a bettor with an edge and a bettor with a good month.
You need at least 200 bets at flat stakes with complete, honest records. Only then can you measure ROI and CLV reliably enough to separate a real edge from variance.
A month is a small sample dominated by variance. Winning stretches happen to break-even and losing bettors too; a durable edge only shows up over hundreds of bets.
Attribution is breaking your record down by situation — say, NFL home underdogs versus NBA totals — so you can see exactly where your edge is and isn't. That's where real improvement comes from.
