I think Hambini's point in his discussions of the watt losses is not necessarily to sell his BB's. His criticism's are valid when it's the manufacturers who consistently tout the watt gains of their products due to their company's detail to "wind-tunnel" testing and expensive CAD designs. His point is that all of that "amazing" engineering is lost for good if you can't efficiently manufacture your bottom bracket bearings to line up as to avoid stresses. It's the dirty little secret they don't want you to measure. Instead, you're supposed to be impressed by the flash and beauty of the frames they have. It's good to have a really good frame and components. It's much better to lose weight, eat good, and train properly.
