I believe that certain programs do NOT score that well by using some of the
Arena Opening Books available, due to the fact that the program doesn't know how
to best continue a line that was chosen by a GM with a long plan of how to best
continue into the middlegame once the Opening book line end. Therefore, no
general opening book should be longer than 10 moves. But certain program benefit
from such opening book like Slowchess 2.94.

PS: I did noticed that Slowchess 2.94 doesn't play those opening lines
automatically, but instead it take a couple of seconds checking to see if the
next move will place Slowchess into deeper trouble or it will benefit from using
the provided line of the Mainbook of Harry Schapp. I don't know how many
programs check for a few seconds before it decide to use or not to use x Opening
move lines.
