THat's the reason why we're not publishing them yet. :) Unless we really see an
improvement like the 5500->5555 step, we don't want to recommend any special
settings.

How can you tell? If you are judging by the depth CM shows, I think you may be
wrong. I have always wondered what exactly the numbers mean, but x/y does
definitely *not* mean "x ply brute force, y ply selective"!

I have used many personalities where these figures showed things like "1/12"
after 2 minutes, and you don't want to suggest CM is looking only 1 ply ahead
brute force!?
My feeling is that the second number is the ordinary ply depth whereas for the
first, I have no clue (the manual isn't really informative about this either).

You can see the selective depth is much higher than 12 by looking at the
variations CM is tossing out.
Also I am not sure what the "Selective Search" slider actually does, i.e. if
SS=6 really means "sel. depth = brute force depth + 6" or if it is just some
relative number like the "playing strength" slider.
