7% KWD Trumps 4.86% KWD and the page with no mentions but 1 contextual back link!

So - the story so far has changed!

The low density, many mentions page has indexed but is NOT found for the target keyword at all.  The no mention, but 1 contextual backlink page is indexed - but is NOT found for the target keyword.

So in order for the target keyword we have four results

#1 =  The 7.01 % Density page
#2 =  The 4.86 % Density page
#3 =  The 1.95 % Density page
#4 = This page! (Density 2.70)

Now this is clearly a bit odd - this page should trump the 1.95% content page - what is different? 

1. It has more indexed content - probably gives it more authority.

2. It has contextual links pointing outward with the target keyword.

Now I find it surprising that these elements would effect this in this way.  I still find it surprising that the contextual link to the page with no mention of the target keyword hasn't gotten it indexed.

I will give it a little more time, and it nothing seems to start happening I will build 5 backlinks to the non-mention page and see what effect that has.
