Hi, Astrid! Starters are each unique living things, and they grow at different rates, so it's quite possible that you have a starter that's more active than PJ's! This just means that you'll find your loaves rising more quickly on average, which can be quite handy if you're in a time crunch! If you find you need a foil tent, go ahead and do that. Sourdough definitely keeps us on our toes, and being adaptable is the best way to get the most delicious loaves from our own kitchens. Happy baking!
