That blog post is confusing. Are you filtering out multiple results from a domain or not? It doesn't look like it from what I'm seeing.
So if a #1 listing has sublinks below it those are counted towards the ranking, which is kinda stupid, but it doesn't always do this so then it becomes confusing and inconsistent. eg. #3 will go to #6 and then back again a few hours later.
M0rtal, the old method for rankings 50+ would filter out multiple results from a domain as it used the 100 results per page method. Any ranking above 50 uses the standard Google 10 results per page with no filtering for the most accurate results possible.
The only affect you will see on rankings is a higher accuracy from 1-50 and maybe a few rankings difference anything after that.
Make sense?
