This doesn't seem right at all. Not only are you people winning in the raw scores, the peripherals seem to indicate that you should be winning by even more. I suspect league-wide tampering and collusion.
Rankings points are calculated by awarding sixteen points for first place, fifteen points for second place, etc.
Luck +/- is calculated by subtracting the ranking in the standings from the ranking in the points. So, if you're fourth in points and third in the standings, you're getting slightly lucky and will have a +1 Luck +/-. So, a positive Luck +/- will indicate that the team has been getting lucky, while a negative Luck +/- will indicate that the team has been getting unlucky.
If your Luck +/- is -6, you're Sandy. Sandy, if you've been practicing ancient spells of black magic, I suggest that you stop. If you haven't, I suggest that you start. Or maybe it's just retribution for sullying the name of His Intangibles.
Philip Humber is currently on pace for five perfect games this season, if we assume thirty starts. If he gets even halfway to that projection, look for Catch These Men to be on the move.
