Heading levels in a UG

I agree. I've read more than once that one should try to stay within three 
levels of headings (not counting book or chapter titles). In the Chicago 
Manual of Style, all I could find is section1.72: "Levels of subheads.... 
Only the most complicated works need more than three levels."

Six levels would drive me nuts, especially if they have that annoying 
1.1.1.1.1.1. style of numbering. Sheesh!
