  Notice that in this peer case you need not think that the two of you are equal on each Disagreement Factor. On occasion, a philosopher will define ‘epistemic peer’ so that \(X\) and \(Y\) are peers on belief \(B\) if and only if they are equal on all Disagreement Factors.  If \(X\) and \(Y\) are equal on all Disagreement Factors, then they will be equally likely to judge \(B\) correctly, but the reverse does not hold.  Deficiencies of a peer in one area may be accounted for by advantages in other areas with the final result being that the two individuals are in an equivalently good epistemic position despite the existence of some inequalities regarding particular disagreement factors.
