3. WHAT THIS MEANS
Good bettors still lose a lot

Even with a strong edge, brutal losing streaks are part of the game.

Win rate alone means nothing

Odds, staking and variance have a huge impact on your drawdowns.

Survival is the edge

Most bettors fail emotionally during downswings. Stay patient. Stay sharp.

Reality Check

55% win rate at 2.00 odds = very strong bettor.

Still expected to experience:

Multiple 3-loss streaks
Occasional 4-6 loss streaks
Rare 7+ loss streaks
Painful drawdowns
What does this look like in perspective?

Even great numbers don't protect you from variance.
