I was just researching for this info for a while. Following 6 hours of cituonnous Googleing, at last I got  it inside your web site. I wonder what's the lack of Google approach that do not rank this style of informative  websites in top of the list. In general the leading web sites are full of junk.
AFAICT you've coeverd all the bases with this answer!
