I have to agree with claaarky - I had several (hundreds) of #1 rankings that dropped to 5-10 in the first panda and lost 60-70% of my traffic overnight overall (so about 85% of organic google traffic)- most of the traffic percentage from those top rankings.
A drop from #1 to #6/7 is devastating when it is across the board. In fact, I would bet that a drop from #1 to #5 is much worse (in percentage of traffic lost) then a drop from #11 to page 3 or even further.
On another note - is it possible that traffic losses this past week could be due to storms in the eastern U.S.?
