336x280 showing 4 ads again

seems google adsense has made some tuning, now my pages using the large rectangle ads are showing 4 ads again.

In the previous month, google has decided to show 2 ads in the large rectangle only, claiming this will increase the publisher's revenue. (See my previous post). What I can see was many webmasters were complaining the new layout has ruined their page design.

Though the overall revenue has not changed much, and webmasters generally receive higher CTR, Google realize the change is not benefitial to us or to herself, and now they decide to tune it back to 4 ads.

Now my ads are showing 2-4 ads, in which it has been always 2 ads in the past month. Im happy to see this changes / rollback, and Im awaiting to see what changes it will bring to my CTR and revenue.
