It looks to be wrong on this particular mate score:

               33->  23.02 -Mat18   1. ... Bb3 2. Kb2 Kc4 3. b5 axb5 <EGTB>
                                    (s=9)
               34    23.04 -Mat18   1. ... Bb3 2. Kb2 Kc4 3. b5 axb5 <EGTB>
                                    (s=8)
               34->  23.51 -Mat18   1. ... Bb3 2. Kb2 Kc4 3. b5 axb5 <EGTB>
                                    (s=9)
               35    23.53 -Mat18   1. ... Bb3 2. Kb2 Kc4 3. b5 axb5 <EGTB>
                                    (s=8)
               35->  24.07 -Mat18   1. ... Bb3 2. Kb2 Kc4 3. b5 axb5 <EGTB>


This is a cute "classic draw" that becomes a win by forcing the rook pawn to
become a knight pawn due to zugzwang...  If white had one less pawn, this
wouldn't happen.
