Are we supposed to assume that when a dough reaches the point that it windowpanes, the dough has enough strength?  I let my white sourdough reach just that point in the mixer the other day, and did not fold it.  It seemed a bit slack to me, but I was experimenting.  The result was a slack dough that spread quite a bit in the oven. (I did the final proof in a banneton.)  I have also taken that same formula and given it folds to the point that in the oven, it bursts because it's too strong.  How do we assess when I dough has hit that magic point of being strong enough but not too strong?
