Yeah, experience matters. But whether it's learning to walk as an infant, baking bread, or having sexy sex, the more experience we have at doing something, the better we tend to get at it. As the old saying goes, "We tend to get good at those things we do often."

Volume is good enough. People lose sight of "just how good does good enough really need to be?" What you are talking about is a discussion of tolerances. I used to be a toolmaker. Perfection in accuracy and tolerances was part of my stock in trade. So many wasted hours spent telling customers that no, the tolerances do not need to be +.0005"/-.0000" or +.001mm/-.000mm for this or that it needs to be this accurate to function correctly. if you insist, I can do it your way, but you will be very unhappy.

When I bake my 2 loaves of bread at home, I use either cups and spoons or a digital scale depending on my mood. I honestly cannot tell you the difference in bread quality. Perhaps I'm just a bad baker and a worse connoisseur of bread - after all, I'm not Paul Hollywood. But I do know it's still far, far better than store bought bread.

I have known 2 different people that owned and operated very successful family bakeries. They didn't much care about weights of ingredients in the kitchen much beyond accounting costs per loaf to determine pricing. At 3AM ain't nobody got time or the mood to scale everything. But yes, they did understand the dough itself allowing them to worry less about the exact measurement. We tend to get good at what we do.

Is baking as loosie goosie as cooking? Oh hell no! The tolerances must be respected. But you got more leeway than you, the home gamer, think you have. So worry less, and bake more!
