86, if you point out to me specific sources that can't be used and why I don't use them.  I considered black belt magazine a reliable source.  I now know what a passing mention is.  I went over to RS once as suggested and it was such a long read and confusing I said forget it.  When I put up a post and you or someone says its not reliable, check to see if I put it back up.  The black belt magazine that you said was copyrighted, I showed that link to an admin and they didn't say it was a bad link.  First I heard about it.  Did you see me put it back up? nope!  It is only to show that Ron Duncan was a noteworthy martial artist.  Past that, he's been dead for a few years.  The website is run by his son (I believe), so it may not necessarily be self published.
