Roads to GS titles: Toughness Coefficient (since 2000)

Roelc suggested this method in "Average ranking of Champions' opponents..." thread.
So, the method is:

Therefore, the higher your opponent is ranked, the more points you get. I did calculations

Appreciate your effort (it must have taken a lot of time), but I stopped reading here:

Year.....Event............................. Champion...........................Coefficient

A single flow'r he sent me, since we met./All tenderly his messenger he chose;
Deep-hearted, pure, with scented dew still wet - One perfect rose.
I knew the language of the floweret;/'My fragile leaves,' it said, 'his heart enclose.'
Love long has taken for his amulet/One perfect rose.
Why is it no one ever sent me yet/One perfect limousine, do you suppose?
Ah no, it's always just my luck to get/One perfect rose.

Henin beat three players outsite the top 100 in her first three rounds last year. Sure, she beat Serena, Venus, and Svetlana at the end, but you have to look at OVERALL toughness and not second-week toughness.

Re: Roads to GS titles: Toughness Coefficient (since 2000)

I failed to understand how defeating #1 alone (1/1 = 1.000) is worth the same as defeating, say, #2, #3 and #6 COMBINED (1/2 + 1/3 + 1/6 = 0.500 + 0.333 + 0.167 = 1.000)

Re: Roads to GS titles: Toughness Coefficient (since 2000)

sorry but all these formulas are dont work..take for example 2 draws

wimbledon 2008 draw for niya-
qf- [8] chaky
sf- [2] jj
final- [1] ivanovic

or

wimbledon 2008 draw for niya-
qf- davenport
sf- [8]venus
f- [7] serena

acorrding to the forumla the first draw is way harder...but any tennis follower can tell that the second draw is harder

Re: Roads to GS titles: Toughness Coefficient (since 2000)

interesting list...but Serena, Venus and Sveta make up for the early 3 rounds at the USO 07

there is a bigger gap in the quality of Serena, Venus and Sveta over Schnyder, Jankovic and Safina, than there is in the quality of Arvidsson, Safarova and Wozniacki over Goerges, Pironkova and Makarova

Marion Bartoli

Tennis player of the Millenium

Grand Slam Finalist | Career High Rank #9 | Queen of the Injury Time-Out

Venus | Dokic | Kirilenko | Robson

Re: Roads to GS titles: Toughness Coefficient (since 2000)

intresting because i consider 2004 after the oz open as 1 of the worst grand slams wise for a very long time, and the 3 slams mentioned are in the bottom 7!

Anna Chakvetadze Rules

Kim Clijsters - Supporting the comeback!

I have no other faves, I just hate

Well, at least Venus is at the bottom, so in that sense, the list is right

Kuznetsova doesnt make up for anything. Kuznetsova is horrible in finals, chokes against Justine and played possibly the worst match of her career in the semi finals where she was fortunate to get an opponent who played even worse. Her ranking was irrelevant, there was no doubt in my mind she would get slaughtered in the USO final.
