For example, if a team scores 75% of the total points and only allowed 25% of the total points throughout the year, would we only expect that team to win just 75% of their games?

A z-score of 1 or more means that there is a 68 percent chance that the 100-win team is actually better than the 90-win team. Rounding one standard deviation to the nearest whole number (six) means that an average teams record would range from about 7587 to about 8775 about 68 percent of the time (reflecting the proportion of the area under a bell-shaped curve within one standard deviation of the mean). Two standard deviations correspond to 12.72 wins. There are occasional outliers, illustrated here by Cincinnati in 1961, which won 10 more games than its Pythagorean prediction. Third-order wins are second-order wins that have been adjusted for strength of schedule (the quality of the opponent's pitching and hitting). From these numbers, I created five important takeaways to be interpreted from the data. The fact that accurate formulas for variable exponents yield larger exponents as the total runs per game increases is thus in agreement with an understanding of the role that chance plays in sports. Are the Red Sox as Good as Their Record? - Boston Red Sox Jacksonville is another team that you have been able to pencil in the negatives for a while now. Since in the quality model any constant factor in a quality measure eventually cancels, the quality measure is today better taken as simply the wins ratio itself, rather than half of it.] Baseball-Reference.com, for instance, uses 1.83 as its exponent of choice -- a modification that has successfully narrowed the formula's margin of error.
