Everyone asks: "How many bets until I know if my system works?"
The answer isn't what you want to hear.
The Uncomfortable Mathematics:
To detect a 10% ROI edge with 95% confidence at average odds of 2.5:
You need approximately 1,100-1,200 bets.
To detect a 5% ROI edge:
You need approximately 4,000-4,500 bets.
Why This Ruins Everything:
Most betting systems claim 15-20% ROI.
If that were true, you'd see clear signal after 400-500 bets.
But they don't. They collapse after 300-400 bets.
What does that tell you?
The claimed edge never existed. It was variance.
My Bet365 Bot Reality:
After 832 bets: 7.33% ROI
By statistical power calculations, I need ~3,000-3,500 bets to prove this edge exists with confidence.
But I'm stopping at 1,000 for transparency test purposes.
What does 1,000 bets tell me?
Whether ROI is positive or negative (yes)
Approximate range of edge (ยฑ3-4%)
Whether it's worth continuing (maybe)
What it doesn't tell me:
Exact edge with high confidence
Whether 7% will hold long-term
If this edge will persist next year
The Industry Secret:
Nobody runs 4,000-bet validation because:
Takes 12-18 months minimum
By then, market conditions changed
Model might need retraining
Can't sell "unproven" system for 18 months
So they test 200 bets, call it "proven," and start selling.
What You Should Demand:
Minimum 1,000 verified bets before trusting any system.
Preferably 2,000+.
Anything less is a marketing pitch, not evidence.
