ATS opening

I am curious how many RO got their results changed (just the move order) from 3-ply to 4-ply.

In my other post, I addressed opening rolls for money. It occurred to me that you might be interested in AtS differences as well.

To my knowledge, only four opening rollouts have thus far been done AtS on both XG 3-ply and 4-ply: 21-s, 41-g, 51-s, 63-s. Here are the comparisons:

    43
    s[U Z7 S8 D12] <25
    s[Z S1 U9 D16] ^46*10 5

    51
    s[$ S2] <5
    s[S $7] ^27

    63
    s[R=S] <5
    s[S R6] ^12

    41
    g[$ S9] <28
    g[$ S2] ^46

So far, there is a surprising amount of difference between the 3-ply and 4-ply results, but we'll be getting more data as the (4-ply queue) reply assignments finish and the AtS positions start getting rolled.
