Ritchey has a Fit Logic poster available to retail shops by mail and to anyone via downloadable PDF. It explains their philosophy behind the range of sizes, angles, widths and drops on their road components (stems, handlebars and seatposts). It’s a bit of a bummer that it doesn’t get into how to choose the right sizes, particularly with regards to handlebar width and drop, it’s still something to look at besides those TPS reports you’re toiling away on.
