Part of the art of making bread involves knowing when to add and when not to add anymore flour. It's not uncommon to need less then what a recipe calls for or more then it calls for. You only add enough flour so the dough clears the bowl (for most breads). Over mixing and under mixing also heat up some doughs and change how they handle flour. It can all get rather technical, to say the least.
But if you have the patients to experiment abit watch how much flour your adding closely. For instance for 1 loaf of bread (a really small batch) could need almost a 1/2 c. less flour than the recipe calls for. Moist doughs are better tasting loafs then drier doughs, so you don't want to add any more flour than necessary. The whole item can go from a so-so yeast product to a great one with the right amount of flour. Breads are not like other baked goods in this regard, they are about feel and getting ther right texture.
Just some food for thought....
