More than you had ever thought possible.

After I wrote this piece, this topic came up at Fangraphs as they use Tango’s formula. So I checked the 1961-2003 data (excluding 1981 and 1994) and found that the +3 intercept had a slightly lower RMSE in predicting W% (3.949 to 3.951 per 162 games). I was a surprised by this, since the teams in the sample had a mean RPG of 8.74, and the tangent line I took was at RPG = 9. I don’t have an explanation for why this is, but I’ll pass it along anyway.

If this isn't your cup of tea, there are plenty of other sites out there for you to try—we're not going to be for everybody, and we're not going to try to appeal to the masses." —USSM
