A closeup of version 1.0 of the leveling blocks. Secured with other blocks and boards and nails.
Version 2.0, secured with construction adhesive. Both of these sections were really low, low enough to accommodate another whole 2x4 thickness plus another chunk plus some thinner pieces plus some wedge shims.
Version 3.0, frickin frickshun. The little chunk of cement-board at the bottom center was my marker as I tried to remember where I'd just measured.
