625 / 664 = 94% whole grain.

10:26 am. Bake UNcovered, 420/400 F, 20 minutes.
10:46 am. Bake uncovered, 400/380 F, 10 minutes.
10:56 am. Internal temp 210.0 F. Total bake 60 minutes.
Virtually no oven spring at score lines, they weren't deep enough. There was some oven spring over-all as evidenced by exapansion cracks throughout the top crust. Ergo, final shaping was too weak and didn't form a good gluten skin/cloak.
I should have left it in fridge, as the expansion during the room-temp final proof was too much.
I always let boules cool upside down. This was the first time the upper crust collapsed.
