[CaseStudy] Help with Penguin case study

I've been analyzing my domains that got hit and they all got hit on some keywords but are ranking just fine on others and I think I'm beginning to see a pattern.
This could of course be all a big coincidence that why I need help from you guys that got hit.

You need to have a domain with at least two keywords that were ranking equally high with equally same competition, with one keyword that got hit and another is doing fine.

For example.
2 keywords on Page 1 with medium competition or 2 keywords on page 2 for hard competition, one slapped other one still ranking on same page.

Send PM is you're interested.

What?

lol...I should have probably waited until tomorrow instead of posting this at 5am so I could make some sense.

I am looking for someone that got slapped on some keywords but are still ranking on other keywords on the same website after the penguin update and want to share the keywords and URLs for a case study.
