And the sgf is different again from the HTML

2-ply cubeless equity    +0.657         (Money:  +0.653)
        74.0% 18.9% 1.0% - 26.0% 2.6% 0.0%
Cubeful equities:
1.      Double, pass    +1.000  
2.      Double, take    +1.033  (+0.033)
3.      No double       +0.847  (-0.153)
Proper cube action:     Double, pass
