As Slojo suggests - just get on with it!
If you keep an accurate record of weights and method each time you make the formula then after 15-20 tries you'll start to deviate from the base recipe - some won't work so well, and others will be better.
Provided you stick to the same brands don't add far too much (or too little) yeast and/or water then you'll start to see a pattern emerge that tells you a lot about how the dough is responding. I up to almost 185 goes at making baguettes and I'm still refining the way I make them even though the ingredients formula is the same. For a full-time baker this is only 6-months of experience, so hang on in there!
Just don't get disheartened - even a not so perfect loaf or roll is often far better than supermarket (almost always) or artisan bread (depends)
