Yep, we’re all on the same page. Unless you get up around 5% of the total flour weight in whole egg you won’t notice any change in taste or texture of the finished crust and even at that level (2-pounds in a dough based on 40-pounds of flour) you won’t see any difference in the way the dough handles, BUT it will impact your dough in other ways, beginning at about 2% it can cause your dough to color faster in the oven, much like adding sugar, it will also make your dough more expensive to make (nearly a dozen eggs per dough), and since we’re talking about fresh, shell eggs, it will also contribute to an increased potential for cross contamination (not good for business).
