After a couple of epic fails I think I'm getting close. Here is what I made this weekend:
70% water, 1% IDY, 2% salt, 1.9% DMP, 540g dough in a 14" x 10" pan TF = 1.36. Mixed, kneaded, and pressed in pan and proofed for about 8 hrs at room temp. Had to pop some bubbles now and then. Pre-baked crust at 500 for 10 minutes, topped then back in the oven for another 10 minutes.
Hopefully this wasn't just blind luck, I'm going to try again this weekend to see if I can re-create it!
