Drop from #13 to #100 in one site, rise to #5-#1 in other site(graphs, ratios included), thoughts

I got my first major penalty since starting SEO&IM in may. However i simultaneously ranked 2 sites on page 1 with a slightly different method. Combination of gsa ser, and expired web 2.0s. I think what fucked my one site was an unnatural url% ratio.

Ill go over the details below.

Penalized site:
3,000 searches/month amazon
created may 1st
5,000 words content on the site
On May 5th I bought diversity package(no pbns) from BHW. Then by late june it was solid at rank #13 for most keywords….
