Remember breweries have expensive laboratories, so they can accurately measure when each step is done, they can control their processes with great accuracy. To a homebrewer, a few percent here or there don't really matter. For a large craft, a few percent is huge, so they study process and literally turn the process into a science.
Give a man a beer, waste an hour. Teach a man to brew, and waste a lifetime! Bill Owen quote
