I took a bit of time tonight to tweak the level of the slab. It’s quite flat overall, though there is a tiny bit of ‘fade’ toward the front, where it drops a tiny bit. I did a bit of tweaking with some shims under the back edge to get the rear half or so of the slab as flat as possible. That’s where the bookcases and corner cabinet will rest on the slab, and the flatter it is the less tweaking I’ll have to do when I install them.
