comment Compute the expected value of the next step of a sorted random walk
@Barry: I am sorting deterministically, taking the earliest case of a value first. That is, if $S_i = S_j$ and $i<j$, then $S_i$ appears before $S_j$ in the sort order.

comment Compute the expected value of the next step of a sorted random walk
@Barry: For N=4, there are four expected values to compute. The expected step after the "smallest" position is 12/16; the expected step after the "second smallest" position is 2/16; ...; the expected step after the "largest" position is -10/16. Does that make sense?
