There are roughly three kinds of people who bet on sports and horse races. The first, and by far the largest, loses money. The second breaks even over time without realising it, because the entertainment value masks the slow bleed. The third, a very small minority, treats it as a serious discipline and makes it pay. This book is for the person who wants to be in the third group — or who already is, and wants to stay there.
If you close this book energised to go place more bets, you have misread it.
Chapter 12 covers why tracking matters and what to measure. The Long Edge Bet Tracker is the tool that does it — a Google Sheets template with the same principles baked in.
It handles Kelly sizing, calibration scoring, closing line value, bankroll management, and performance breakdowns by sport, bookmaker, and source. It tells you when your sample size is large enough to draw conclusions, and when it isn't.
One-time purchase at $99.99 — or bundle it with the book for the same $99.99, and the book's free.
This book comes from the operator behind MrWorldPool — a betting product for serious horse racing pool bettors covering Scandinavian, UK & Irish, Hong Kong, UAE, German, and Japanese racing.
The material comes from years of daily use across those markets, plus selective betting on football, tennis, golf, and prediction markets. The companion bet tracker started as a personal tool and became a product when enough people asked about the process behind it.
Neither the book nor the tracker will make you a winner. They give you the framework and the measurement tools. The edge is yours to find.
