I am also interested in the amount of ads per page and size of ad. Particularly # above the fold and inside/outside of the main "content" area. Before Panda 1.0 compared to now.
Just to confirm, you had a drastic drop (~60%) in traffic on February 24th?
Also, what kind of recovery did you have? Was it gradual from July on, or was it pretty much instant in the last couple of days?
