Yes; I got the answer from PRG support on 2nd Apr,2014.

For d/D = 0.47 near to 0.5 limit of note 11 of B31.3 App-D & D/T = 83.9, out of plane SIF is much higher than B31.3 App-D,

So, the result is not surprisingly odd! Perhaps, we rely too much on WRC-107, 297, B31.3 App-D even beyond their area of applicability!
