Given a branching factor of 3, and a doubling of speed, should the elo increase at a declining ratio of 2:3 relative to depth? If that's true, it seems that to maintain a constant elo increase per some speed increase, that the speed change should be equivalent to the branching factor. That's assuming one believes that each ply increases strength by a uniform amount, regardless of depth. Which could be theoretically true, but I suspect people tend to lop off more given more depth.
