Gaviota is happy to agree with YACE:

215817 9 1.1 :-) Bh3-e6
250398 9 1.3 +Mat_9 Bh3-e6 h7-h6 Kg5-f6 Kh8-h7
Kf6-f7 Kh7-h8 Nh5-f4 Kh8-h7
Be6-f5 Kh7-h8 Nf4-g6 Kh8-h7
Ng6-e5 Kh7-h8 Kf7-f8 h6-h5
Ne5-f7
1134149 9: 6.3 +Mat_9 Bh3-e6 h7-h6 Kg5-f6 Kh8-h7
Kf6-f7 Kh7-h8 Nh5-f4 Kh8-h7
Be6-f5 Kh7-h8 Nf4-g6 Kh8-h7
Ng6-e5 Kh7-h8 Kf7-f8 h6-h5
Ne5-f7
6157119 10 33.8 +Mat_8 Bh3-e6 h7-h6 Kg5-f6 Kh8-h7
Be6-f7 Kh7-h8 Kf6-e7 Kh8-h7
Ke7-f8 <-transp
12262859 10: 69.3 +Mat_8 Bh3-e6 h7-h6 Kg5-f6 Kh8-h7
Be6-f7 Kh7-h8 Kf6-e7 Kh8-h7
Ke7-f8 <-transp
26015857 11 146.8 +Mat_8 Bh3-e6 h7-h6 Kg5-f6 Kh8-h7
Be6-f7 Kh7-h8 Kf6-e7 Kh8-h7
Ke7-f8 Kh7-h8 Nh5-f4 h6-h5
Bf7-g8 h5-h4 Nf4-g6
Which makes me happy too to see reasonable and stable numbers since
I tuned the way I adjust the mate scores. Seeing mate in 9 and then 8 is ok.
