It is a matter of scale, it is essential to measure accurately for commercial products that do not tolerate loss of bread/pizza etc. For home baking you have many challenges, from the oven temperature (less than ideal and the dutch oven is meant to simulate commercial oven conditions and temperatures at home) to protein content of flour. I do not measure anything for baking bread or pizza because I use it as therapy not as a chore.I bake pizza with love, by taking my time and adding the best ingredients I can get, from wheat germ to best quality flour and fresh Mozzarella. The family has voted, my pizza is better than any delivery they have ordered.

Ooh I've thought about doing that. Totally makes sense since egg sizes range a bit.

And the best cake maker I know whips ingredients together by her mood, inventing cakes on a whim. The margin of error is wide enough.
