This tool shows why lower-scoring sports feel swingier to bet. Holding your edge constant, fewer scoring events (soccer, hockey, baseball) mean higher variance in outcomes—one goal or swing can flip a bet. Use the controls to see how ROI dispersion and “time spent underwater” change as scoring intensity drops.

Not all edges feel the same. In low-scoring sports, a single event can decide everything, so variance dwarfs your long-run advantage. This calculator simulates that effect: set a scoring rate, pick a price, and see how often you’ll be down—even with a positive edge—and how wide your ROI can swing.
