How I computed my final standings:
Games won + f(r) (calculated wins of remaining games) = total games won.
f(r) (calculated wins of remaining games= (162-r)X ((sqrt (Win percentage X Win percentage last ten games))+ f(e)(%Error of win percentage total)).
f(e)(%Error of win percentage total))= 1.29 X sqrt((Win percentage X Los percentage)/(total games played-1)).

Given the variables involved, might as well just use informed judgement, and besides most guesses, or models, or anthing, are going to be within 1 or 2 W or L of the actual outcome with so few games remaining.
Essentially you "computed" that since the Yankees have a better L10 record, they're going to win the division. That's a valid opinion, but it has nothing to do with computation.
