Nack: If you turn the option ON, then XG splits the rollout (from two candidates) into four candidates: (a) 61P-22N, (b) 61P-22E, (c) 61P-22N-C-T and (d) 61P-22E-C-T (where C = Cube and T = Take). The rollout continues until it becomes “clear” that (a) or (c) is doing better, and/or that (b) or (d) is doing better. For example, say that (a) and (d) are doing clearly better; in that case, (b) and (c) are dropped, and the rollout finishes with just (a) and (d), and XG reports only those two candidates in the results.
You are close Nack. a and b will always be rolled the same number of time, no matter what, same for c and d. At the end the system jsut pick what is the best choice: a or b
Here is how it will be displayed in the analyze dialog for XGID=---A-bD-C---cD---c-eA-b-B-:0:0:1:51:0:0:3:0:10
