Query: A big disappointment

I have this author's older book, "The Bread Bible," and love the book. I anticipated that this book would be as good but for the bread machine. I have a 1 pound machine and was surprised to find all recipes in book are for larger loafs. She instructs to just halve the recipe (2lb) to make the 1 pound loaf, but after my first attempt to divide 1 7/8 and 2 5/8 I gave up. I'm not a complete math dummy, but I don't care to do this math every time i wish to bake a quick loaf of bread. A couple of recipes that were evenly divisable, I did try and they could not have been tested. Don't waste your money.
