I can live with winning 2 out of every 3 game series we play. That's a .666 winning percentage which would lead to 108 wins for the season.
We've won 2 out of 3 games every series since Opening Day; we won that "series" , 1 game to none.
So our pace, at 11-5 and .688, is actually more on the order of 111 wins.
We've played 16 games, so we have to multiply by 10.125. It'll be easier after two more games, after which we will have played 18 games, and then we can just multiply by nine with no fractions involved.
We'll meet other "even-number" milestones at:
Game 27 - multiply by 6
Game 54 - multiply by 3
Game 81 - multiply by 2
