Hi
I rolled out the starting position 50.000 times using Jellyfish
Level 5 to produce the table below to show cubeful distribution.


Cube Level        1       2      4       8      16      32      Total
Cashes          37.83   13.54   1.78    0.28    0.03    0.01    53.47
Single           0.00   26.63   5.03    0.59    0.06            32.31
Gammon           1.45    10.9   1.17    0.10    0.01            13.63
Backgammon       0.07    0.46   0.04    0.01    0.01             0.59
                                                               100.00

Just in case it's not clear. Cashes are games that end with a cube
turn.  Singles Gammons and Backgammons are games played to conclusion.

I'm not technically minded enough to make use of these numbers, but
would they maybe affect match equity tables etc or could they shed
any sort of light on recube vig?
