What has this subdomain done to recover from Panda?

I found that doctor.webmd.com was affected by Google Panda, and then recovered (if you look at traffic on compete.com). What do you think they did to recover?

My "opinion" is that the website was slightly affected by the Panda update, and than a week or two later it started to gain back it's rankings or traffic.  This has been the behavior of many large websites after the first Panda update and it's continous updates, you would see a drop in traffic than couple weeks later it will level back off to it's usual traffic numbers before the Panda update that caused a slight drop.

I most likley might be wrong here, but I am just making an assumption from observations I have seen on other websites.  Also from my understanding, subdomains are not as powerful as they use to be and are not really favored as much from the new "Panda" update.  I believe the preferred site architecture now is using sub-folders.

I apologize if any of my statements above are false, and if they are please correct me.
