It's very helpful! Thank you! So are you saying that you don't use any sugar in your dough? I've been using sugar, letting it sit at room temp for about 4 hours then holding it in the fridge for about 48hrs.
Diastatic malt is sugar, and enzymes to convert a little of the starch to sugar. (nothing wrong with that.) The sugar is what helps with browning.
You can make dough without any sugar at all. I'm not sure if baker's yeast can break down and digest some of the starch, or if all flour has a little malt in it.
