The Power Index Leaders Thread - updated after Miami.

Bombshell: Justine has more power than Serena and Venus. The end of one of the biggest biases on WTAWorld . Interestingly though, both Justine and Serena as well as Venus have been playing (significantly) less powerful at the beginning of this year than at the end of last year.

http://www.sonyericssonwtatour.com/2...ex/default.asp

Since they redesigned their site, the WTA website has a new (cool) feature: The Power Index. It's in the Players menu. The Power Index rankes the top-10 players who executed the most power while playing, in other words the ten most powerful players, duh. However, the speed of the ball is only measured at center courts. After every tourny whith the capability to measure the speed of the ball, the new Power Index is released. The last one was Miami, or else it's not been updated yet.
Also, the 10 best players' averages over the last 4 or 5 tournies are listed in the Power Index Leaders.
Hopefully, the Power Index will be updated after Berlin again.
Unfortunately, they are not that precise in telling which tournies are taken into account concerning the average over the last couple of tournies, but perhaps it's just every TI and TII tourn.

"The Power Index is the average maximum hitting speed of any player judged by maximum: a) 1st Serve Speed; b) 2nd Serve Speed; c) Forehand; d) Backhand; e) 1st Serve Return;
f) 2nd Serve Return; and g) Smash."


So here it goes, we'll start with Stuttgart 2007 (unfortunately there's no archive, but this was the first one I copied and saved, at the beginning of this year):

Re: The Power Index Leaders Thread - updated after Miami.

these rankings are kind of weird.
But yes it's a constant myth that Justine isn't power player. She doesn't win in spite of her lack of power, she wins because of it. She has other weapons and she does use her variety but w/out all that power she'd be a mauresmo or a schnyder.

Re: The Power Index Leaders Thread - updated after Miami.

This is no true list without Dementieva, particularly one without her topping it.

Useless rankings. I mean, hitting the shit out of one smash carries as much weight as a consistently big 1st serve.

Re: The Power Index Leaders Thread - updated after Miami.

Re: The Power Index Leaders Thread - updated after Miami.

This proves what us Serena fans have been saying for years now, Serena is a lot more versatile than she's given credit for. Her game revolves around angles, and calculated power, she's not all about BANG-BANG tennis. So I like these stats confirming that. It's even better because she's doing so well and it's obviously not just about power- as you can see.

STEFWHIT'S HALL OF FAME
Greatest Singles Player of All Time: Steffi Graf
Simply the BEST: Serena Williams [Proud MEMBER OF RENA'S ARMY]
The REAL GOAT Rafael Nadal
Future Inductees: Clijsters, C.Evert, A.Agassi, A.Berasategui, N. Zvereva, I.Majoli, M.Safin, Li Na, VIKA, and Del Potro

Actually, it was never a "myth that Justine isn't power player", its a fact!
Though rightfully so, Justine only become dominant a player she is when she incorporated in her repertoire the "power", but she still relies on her shotmaking and variety to win matches. She has work hard to gain "power" thus give her an edge over the other girls. What fascinates the people and the tennis purist is that Justine generates all this "power" often times rivaling that of the bigger girls due to her technique alone!

Comment on the term power, I just want to emphasized that there is a difference between a hard ball and a fast ball. Justine's shots are usually fast while that of Serena and Venus, especially their serves are hard.

Re: The Power Index Leaders Thread - updated after Miami.

I'm surprised Leanne Baker isn't there

She has a fast 1st serve, 2nd serve, Forehand, Backhand, 1st serve return, 2nd serve return and Smash...

.....Oh wait the requirement is that they aren't Unforced Errors

Thank you for everything Mercedes, now please be nice to Socrates for me, perhaps fetch him a bird or two. We love you, always.
