I've ready the same. Also, the protein rest also helps with head retention and body, while the traditional two sacc rests help prevent the beer from getting too thin. A three step infusion mash gets a bit out of hand because of all the water you need to add, so a decoction is a much better way to raise the temperature if you do not have a direct-fired mash tun.
Beer is good for anything from hot dogs to heartache.
