That's a rather different concept, now isn't it?
If no one knows, no one knows. Not like they can test it any better than we can.
If it was common knowledge it'd already be in the wiki.
If you can find yourself someone who plays, has the answer and is willing to give it, feel free to ask them, but you can't blame those of us who've also looked for not being able to give you an answer that no one seems to have or be willing to share.
I'm not blaming anyone.
I'm simply asking has this been asked yet, like that myth debunk? I don't speak Japanese, so my option would be to find those that do and see if they can get an answer, or a JP player from here.
