Iirc what happened with the diagrams was that after they were added some changes were made to Fergus' Diagram Designer which meant that the FEN Charles used no longer generates dots in the images (M&B09 actually got off pretty good here as most of the diagrams there have numbers); Charles seems to have disappeared though so noöne has fixed them.
I agree it's a long and difficult piece of writing, all the more so because of how much it has to get through; and it takes some time to get familiar with (though as you say, there's a bunch of interesting things in there, including stuff which he's thought of by exhaustion that occasionally comes up in these comment sections with questions as to whether anyone's though of this yet). Not sure how easy it'd be to rework though without making it several times longer still… (maybe it'd work as a series of videos??)
