In this study, we attempted to introduce the Pythagorean expectation used in baseball to volleyball. We compared the three prediction models: the Pythagorean expectation used in baseball (Model 1), the Pythagorean winning percentage using an index suitable for volleyball (Model 2), and a model predicts winning percentage based on the side-out rate and breakout rate (Model 3). Results indicated that Model1, Pythagorean expectation, had a correlation with winning percentage in volleyball, but the error was large. and Model3 had the highest prediction accuracy. We named this model that based on side-out rate and break rate the "Nambu expectation".
