I haven't tested these yet but interesting info if the consensus was made across server and zone.

Also I like the note that these findings are not absolutes but these areas listed grant higher drop rates then others and are linked to you sense <item> text info.

Another note 0 is the starting position +1 is one up via up arrow. So on and so forth.
