I have noticed the exact opposite. Pages that used to be #1 in SERPS disappeared earlier in the year when Google decided to make them supplemental. They eventually returned to SERPS when Google modified it's index seach, and for a long time were about position 6 or 7. Now Google appears to treat both indexes as one and the pages are back at #1. So could this "#6 Penalty" be due to the re-emergence of supplemental pages at higher positions?
