This is basically an equation system, I have heard two definitions of Justine that can help us define Serena.

1) Justine is little Serena
2) Justine is a 21 years old Conchita Martinez with a big serve.

Now, let's try to put this in mathematic terms.

What "little" means here? little by age? no, because they are about the same age and I don't think it means Serena as she was when she was "little", so I think little here means small, and if you say small you mean smaller, we can say

S = J * x

where

S = Serena
J = Justine
x = a factor of how much "smaller" Justine is.

Now, the second definition.

a 21 years old Conchita with a big serve. Again, we can use a factor to weight the "21 years old part", I'll call it y and we take out Conchita's serve and add Justine's serve

C = (y * J) - CS + JS

where:

C = Conchita
J = Justine
CS = Conchita's serve
JS = Justine's serve
y = age factor.

if we work this equations we have

1) J = S / x
2) J = (C + CS - JS) / y

wait a moment, we have two J, so we can say

S / x = (C + CS - JS) / y

S = x/y * (C + CS - JS)

what does this tell us?

Serena is Conchita minus Justine's serve + her own serve, multiplied by the relation between Serena and Justine's body and divided by the relation between Conchita and Justine's age.

Gah, that was the exact type of math we were doing afew months ago. Very nice analysis, it should go in your sig.;)

Perfect! :worship:

oh dear.

I think it's trying to tell us that serena is venus minus 18 months and her name and the month of her birthdate and a few inches in height. I hate math. It took me so long to figure that one out.

it's a relief to see that not everybody on this board is a weirdo

Fingon, your site is great. However there's an error in the head-to-head, Monica leads the series 4-3, it's not tied 3-3.

well, officially fed-cup counts
One of the reasons why I run a website with statistics is because I decide what counts and what doesn't. Only official WTA tournaments and Grand Slams, no challengers, no qualifying, no fed cup, no olympics, no exhibition, and that's final :p

If Justine is a 21 year old Conchita with a bigger serve, then that levels the age factor, as both are 21. So that intros the new equation where:
J = z • CS + CO

where CS = Conchita's serve
and CO = Conchita's other skills

Let's assume 21-year-old Conchita's average 1st serve speed is ~90 MPH. Let's say Justine's is ~100 MPH. That makes Justine's serve about 10% faster than Conchita's.
(JS = 1.1 • CS)

So we now have

J = (1.1 • CS) + CO

Now disregarding the listed weights, which have Serena only 4 pounds heavier than Justine, let's assume Serena is 10% larger than Justine. That makes X = 1.1
Hence S = 1.1 • J

Substituting the second equation for J, we get
S = 1.1 • ((1.1 • CS) + CO)
or
S = (1.21 • CS) + (1.1 • CO)

If we assumed 21-year-old Conchita's first serves average 90 MPH, then
1.21 • 90 = 108.9
which is a remarkably accurate estimate for Serena's average first serve speed.

Hence, it could be summed up as Serena is equivalent to a 10% improvement over a 21-year-old Conchita's other skills, plus a first serve averaging about 109 MPH.

I have to disagree, Henin gets a lot of balls back, and uses slice as a good part of her game, but she does not plays that MOONBALL and boring Conchita Martinez´s game, she actually can hit the ball from both sides. Conchita can´t maintain a hard-power hitting rally.
