Is this the weakest bottom half (round 2 onwards) at a Grand Slam in recent times?

Serena, Radwanska, Kerber, Venus are the only players I can see reaching the SF from the bottom half. And there seem to be a lot of random players who will at least reach R3. Esapcially Serena's quarter looks really weak IMO.

Compare and discuss.
