@russ I was making a note about you and had to look up possessive pronouns, because I can’t ever remember if there is a solid rule for them, and realized I had never asked someone if they have a preference for their own name. As a token “s”-ending named person, do you have a preference?
Russ’ or Russ’s? 
Wow, I have no opinion on this. According to http://www.grammarbook.com/punctuation/apostro.asp you can do it either way. It seems to me that the most important thing is that the writer is consistent, or at least that a work is consistent.
But wait “Another widely used technique is to write the word as we would speak it”. How would you speak it?
You can’t possibly expect me to write out, “humbly belonging to Russelford U-da-man VI” each time. I’ll stick with Russ’.
I suppose I am fairly consistent with the “s`” pattern, because it becomes a House Slithering situation when I read it with one at the end…
And for the record, I prefer “maiki no” (マイキの).
