You're comparing a third-level domain with a second-level XRI. That's 
hardly fair.

john.alford.smith.name and =john.alford.smith are roughly equivalent. 
The benefit here is merely that you've replaced the ".name" with an 
equals sign. Both have four "semantic units".

john.alford.smith.domain.tld would be more comparable to (for example) 
@domain*john.alford.smith. Again, both of these have *five* of your 
"semantic units", except that in this case a large number of domain 
namespaces (.com, .org, .net and national variants on these) have been 
collapsed into a single namespace identified by "@".

You can't really claim that the global context symbol is not a semantic 
unit while counting the top-level domain as one. I put it to you that 
you are attempting to mislead people.
