All of the above, plus, remember that allowing the dough to rise for even an hour before putting it in the cooler dramatically reduces the ability of the fridge to cool the dough (dough is less dense, making it a better insulator and more difficult to effectively cool), plus if you put the dough in a covered bowl in the fridge, you were again insulating the dough from the cold of the fridge and again reducing the ability of the fridge to cool the dough. Try leaving the lid off of the bowl for about 90-minutes after you put the dough into the fridge, then cover it and kiss it good night. To use the dough on the following day, remove the dough from the fridge, leaving it in the covered bowl, allow to temper AT room temperature for about 2-hours, then turn out onto a floured surface and begin opening the dough into a pizza skin.
