The link states that in effect the same numbers are used in CM or CB AFAIK when
using Malin's adapter. From what I remember though this wasn't the case. Sadly
now my pc's won't run Wb2Uci so I can't check but read the following which seems
to agree.

Note for example the value for King Safety in CM and CB which differ.

"Important Note 1: These settings are mainly played in Chessbase GUI's with the
WB2UCI-Malin Adapter. So don't try to copy the Adapter-values into Chessmaster.
That will not work. It is possible to calculate the values backwards from the
Malin-values; but that is very difficult and for some values just not possible.
I recommend to use for testing the Malin-Adapter because you can work with
values, that are not possible within the Chessmaster 8000-GUI.
Here an Example for the Grailmaster2-Setting:

opp=102 opn=102 opb=105 opr=102 opq=102 myp=102 myn=102 myb=107 myr=102 myq=104
cc=100 mob=110 ks=146 pp=108 pw=126 avd=-4 cfd=0 sop=100 rnd=0 sel=10 md=99
ana=1

Calculated for the Chessmaster-GUI this will something like that:
Attacker/Defender: -4
Strengt of play: 100
Randomness: 0
Max search depth: 99
Selective search: 10 (maybe increase with longer time controls)
Contempt of draw: 0
Material/Position: -3
Control of Center: 103
Mobility: 113
King Safety: 150
Passed Pawns: 111
Pawn Weakness: 130
Own Queen: 9.2
Opposing Queen: 9.0
Own Rook: 5.0
Opp. Rook: 5.0
Own Bishop: 3.2
Opp. Bishop: 3.1
Own Knight: 3.0
Opp. Knight: 3.0
Own Pawn: 1.0
Opp. Pawn: 1.0

However, this values are only approximations because one value for Own Bishop is
not fully correct: Translated into Malin-Adapter it will give: myb=108; but the
number should be 107. So, in theory you have to set Own Bishop=5.15, but that is
impossible. You could reach a number of 107 by setting material/position to -2,
but then all other values will change. So, if you want a possible translations
within the GUI's, go always from the Chessmaster-Setting to Malin and not the
other way around :-)"
