** edit **
I cross checked this with simulationcraft and ended up a similar result. Here's my pawn string for hectic add cleave:
Pawn string ( Pawn: v1: "Jhunk": Class=Warrior, Spec=Fury, Strength=23.09, CritRating=18.97, HasteRating=23.88, MasteryRating=25.75, Versatility=25.43 )
I guess this is possibly due to the slight baseline buff we got ...
