I think you are right. My thing also confirms your feeling:
00:00:05 10.00 -0.14 1.a5 Ng1+ 2.Kd3 Bf2 3.b5 Nf3 4.b6
Nxh2 5.bxa7 (4)
00:00:09 11.00 -0.22 1.a5 Ng1+ 2.Kf1 Be3 3.b5 Nf3 4.h3
Bd4 5.Bxf3 Bxa1+ 6.Bxg4 f5 7.Bf3
e5 (7)
00:00:18 12.00 -0.22 1.a5 Ng1+ 2.Kd3 Bf2 3.Bd4 Bxd4 4.Kxd4
Nf3+ 5.Bxf3 gxf3 6.Ke3 f5 7.Kxf3
e5 8.h3 Kf7 9.b5 Ke6 10.Ke3 (14)
00:00:43 13.00 -0.24 1.a5 Ng1+ 2.Kf1 Be3 3.b5 h5 4.Bb2
Nf3 5.h3 Bc5 6.hxg4 hxg4 7.Ke2 Nd4+
8.Bxd4 Bxd4+ 9.Kd3 (31)
00:02:08 14.00 0.19 1.a5 Bg1 2.Be5 Bxh2 3.b5 Bg1 4.Bc7
f5 (72)
00:04:22 15.00 0.46 1.a5 Bg1 2.Be5 Kf8 3.b5 Ke7+ 4.Bc7
Bd4 5.b6 Kd7 6.Bxh3 gxh3 7.Be5 axb6 (162)
The rise of the score is remarkable.
