Nd2 --> +6,75
Bh3 --> +4,29

I think Bh3 should be added to this test as an alternate solution:

"4.92" bm Nd2
result: Bh3 3600 seconds. score: +6.38 2187766606 nodes. ** error

Bh3 d6 Nd2 Qd8 Bxd8 Nxd8 Rab1 Bd4 Nc4 Be6 Bxe6 Nxe6 Nxd6 b5 Qh4 Rfd8 Qe7 Ra7 Nb7

result(2): Nd2 3600 seconds. score: +6.19 2258383358 nodes.
