Bob,
I guess that is sort of what I am getting at. The 3 other times it was cold, the dough was cold, the marble was cold. I thought the oven spring was not enough before but then again there was the much hotter fire this time.
Maybe I need a row of 230, then 240, then 250 gram so I can try all three with the oven being the same since I am still dialing that in.
(I should make an equal amount of each so I don't have to go crazy with the dough tool, just average them out)
