I tried the cold proof overnight like you describe and the crust was finally as dark as in a bakery. How long do you keep the starter in the fridge between bakes?

Up to a week without feeding. After that, give it two feedings at room temperature before the next bake and it is back to full strength.

Same here, mine survived ten days during a holiday. It smelled sharp but came back after the second feeding.
