Not for me because the branching factor is not important.
Every programmer can get branching factor of 2 by adding some pruning rules but
in that case a ply means clearly less.

I see no special improvement of Tiger15 at long time control relative to Tiger14
based on the ssdf so I guess that the branching factor is simply misleading.
