 This is illustrated in the following example using $\query_1^2$ from earlier.  To aid in presentation we again limit our focus to $\refpoly{1, }^{\inparen{ABX}^2}$, assume $\bound = 2$ for variable $X$ and $\bound = 1$ for all other variables.  Let $\prob_A$ denote $\probOf\pbox{A = 1}$.
 %In computing $\rpoly$, we have some cancellations to deal with:
