目前,很多媒体对于乒超比赛中选手胜率的计算,都使用了单纯胜率统计法。根据这种算法,选手出场次数经常被忽视。一个赛季只打几场球的选手和一个赛季要打三、四十场比赛的选手,如果仅以胜场/(胜场+负场)这样的计算公式来衡量他们的胜率,显然对出场次数多的选手是不公平的,因为出场次数越少,选手的胜率偶然性也是越大的;另外,在乒超目前的赛制上,出场次数多的恰恰是各队的主力选手,而采用权衡胜率在一定程度上也反应了这名选手对球队得分的贡献度。
At present, many media for the ping-pong competition in the calculation of the player’s winning percentage, have used a simple statistical method of winning percentage. According to this algorithm, player appearances are often overlooked. A player who plays only a few games a season and a player who plays three or 40 games a season, if they measure their winning percentage only by the formula of wins / wins (+ negative), obviously the number of appearances More players are not fair, because the less the number of appearances, the player’s chance of winning is greater; In addition, the table tennis current super-game system, appearances and more is precisely the team’s main players, and the use of trade-offs in the winning To some extent also reflects the player’s contribution to the team’s score.
