Consider the attached command file and its result.

A simple race. The initial evaluation says it's a close take, then the rollout progress messages display something like
Player White owns 2-cube: CL +0.55 CF +0.49
which look like equities on a 1-cube.

Finally the export of the final result confirms a CF equity of about 1.

(file #18526, file #18527)

The SE for cube rollouts refer to the double/no-double and take/pass decisions. That may be the misunderstanding here. Otherwise, could you please give both rollout results (no-double and double take).

The "double" equities displayed during a match play cube rollout run from the CLI are incorrect (money play from the CLI and all from the GUI seem fine).

See for instance the attached text with :

Player White owns 2-cube:
0.677 0.203 0.010 - 0.323 0.102 0.046 CL +0.534 CF +0.503
[0.002 0.002 0.001 - 0.002 0.002 0.005 CL 0.007 CF 0.007] r 1.870

0.503 is clearly not 1.87*0.007 away from 1.0 and the final result is indeed rather close to 1.

I think the equities and their SDs miss a x2 factor and then a correction related to the MET.
