Anand is looking even better now :)

I'm sorry to break this to you but you are counting blind games and rapid games and maybe blitz games, whitout counting these the score between Anand and Topalov is I think 2 points apart in favor of Anand.

Edit: Actually before the championship started Topalov was ahead with 11 wins, 10 losses and 23 draws at classical time controls.

So the score is now 12 wins each with 25 draws.

Topa is aggressive with less percentage of draws against everyone compared to Anand

only against Anand, Aronian and Kramnik, topa has less decisive games than draws
