White's current ME AtS is 40%. If she doesn't double and wins she'll tie the match with 50% MWC's for a gain of 10%. By doubling and winning, she'll go from 40% to 67% @ -1 -2 for a net gain of 27-10 = 17%. By not doubling and losing, she'll go from 40% to 25% @ -1 -3 for a loss of 15%. Her overall net gain by doubling is 17-15 = 2%. She can double as early as 17/(17+15), 53%.
