Hah! I'm half the way. I will yet tackle this whale.
Got through the white this morning. To be honest, after that chapter on classification (which promptly put me to sleep last night) it was a piece of cake. Some chapters later he goes into impeaching drawings. The guy loves going into mind-numbing tangents. He's a perfect example of failing at the "no info-dumping your readers with all you researched".
In a perverse turn, I find each time those tangents come around I feel like flipping him a finger and just mutter "I will persevere, you bastard".
