Hey Alexander!
If James won all 18 games, he'd have 90 points.
If James went 17-1, he'd have 85 - 2, or 83 points.
At 16-2, James would lose 7 more points down to 76.
With 78 points, James sure had a good record!

Are you sure that these numbers are right? The answer includes fractions, and I don't know how you win part of a game and lose part of the same game.
