RE: computer-go: Ratings, God and everything.

I supose that the importance of 1 more level will depend on how many
we already have. The practical problem is the branching factor, as 
we can not have full width the pruning is too important. OTOH, ladders
need to be read full depth or assume worst case to play safe which
is not very good.
Finally, to compare moves values and thus error values, as an example
take invading at 3-3 point under a 4-4 stone: the difference between
blocking at 3-4 or 4-3 can go from nothing to more than 20 points.
And 20 points are about 2 stone handicap.

I don't think so. 
If there's something like it may be '3 levels = 1 stone'
