That data was created by Crafty 17.09 running on a 500 MHz PIII at 800 seconds
evaluation time.  Analysis is to ply 13, and centipawn evaluation is +1.2 pawns.

213 million nodes were examinied.  A full second of Deep Blue to get the same
node count.
;-)


If you look at the other evaluation, you will see that the CE is not good.
