@zeus My observations of these last two years of algo changes (and Google hints) is that the highest traffic sites get the updates first and it trickles down to the lower traffic sites after 4-5 days. I can't claim a high end traffic site but the low end ones will usually see an improvement right up front as busier sites get hit (and I say YAY) then at the end of the week those little sites get hit (and I say OHHH). Somewhere in the process, some sites that were in the SERPs with us washed out and someone else shows up.
Low end threshold guess is under 5000-1000 uniques a day.
