Actually I got it!!!

I adjusted the SQLfiddle statement needed a couple extra brackets to complete the addition before dividing by 2:

This now works!!!

((ABS((SELECT MAX(Wins ) FROM WinLossSum) - Wins )) +

(ABS(Losses - (SELECT MIN(Losses) FROM WinLossSum)))) / 2.0 AS GamesBehind

(6-4) + (2-0) / 2

2+2/2=2

You all are awesome!! Thanks so much for this!
