From my experiments, I expect the difference to be larger at longer time controls. At very fast time control (e.g. G/1 or G/2 minutes) there is very little repeatable difference. At G/30 and above, the difference becomes very clear. I have no idea why it turns out this way, because I should expect that the book would matter more when you cannot think about the right move very long, since the book moves should be pretty good, at least.
