OK, in that case, Hradecka has a better serve than Sharapova. When she has a good serving day, she can serve better than Masha. But, my point is that in 80% of matches she doesn't serve the way she did in Madrid. Also, her ground game can be good in some matches, not only her serve. Same with Lisicki and Julia. Lisicki has a huge amount of power in both her serve and groundstrokes, but just like groundstrokes, her serve is inconsistent. Julia too. She hits the fh harder than Ana now, I'm sure about that. But I don't think that her fh is better than Ana's. When it's off, it's awful. And it's off too often.
And having a good serve is what saves you when the rest of your game doesn't work. Venus won the match against Ana just because her serve was great in 2nd and 3rd set (especially on break points), that serve would be enough for Aga too, but she couldn't find that serve the next day. In fact, that's what happens in most of her matches. We couldn't see the match against Kvitova, but before 3rd set her serve stats were very poor, against Wozniak the serve was very bad, but Wozniak choked, in the first set against Ana that serve was awful. Against Kerber and Aga on clay it was bad. It was very decent in Rome, but it was a mess again in Paris.
Ok.. Im not looking at ground game at all.. I think I said Ana has a better ground game than some of these players.. and everyone has off days.. but looking at serve only, all those serves are better than Ana's current serve. Then, when returned the serve and starts groundgame, a lot of these players are very erractic..
But serve alone is a lot better than Ana's.
Obviously, serve alone is worth nothing if you don't have a ground game.. it can only take you so far.. otherwise Hradecka would be top 10. Her serve is usually great, but her groundgame just isn't. It wasn't really the serve that clicked in Madrid, it was her groundgame, it withstood rallies more than it usually does.
All you said just proves my point with the stats.. Ana has a more consistent, arguably better groundgame now than she had at 09/early10/11, yet she has same winning percentage on her serve. Why? Because her serve is worse.. so things balance themselves.. If her serve was better, it would add to a higher winning percentage, and it doesn't. Ana is not super fast or has super high 1st serve percentage like Aga or Woz or Errani to win without depending on the serve, no matter how improved her groundgame is.
