Quantity v. quality
It doesn't take a genius to arrive at the conclusion that a top 10 ranking is gained as a result of beating other top-ranked players more consistently than lower ranked players...
If you do not have the talent, athleticism and sheer will to achieve that, it doesn't matter how often you play - you will never reach that level.
It's like tossing a coin, if you do it a few times, you might get lucky and be able to predict the outcome a high percentage of the time. But, the more you toss the coin, the more likely it is that the law of averages will catch up with you and your true ability of guessing heads or tails will become apparent - that is, that you're going to be right about 50% of the time.
The same goes for tennis matches. You might get lucky and catch a better player on a bad day when they're sick or injured. You might do this several times and achieve some victories that you might not otherwise have achieved. BUT, as with coin tossing, the more matches you play, the more likely it is that your true ability will be revealed and you will achieve the ranking that you truly deserve.
Now, explain to me again how it is that Jelena is only in the top 10 because she plays more matches...
(Actually there IS an answer but let's see how many of you lamebrains - who generate a sense of superiority by criticizing people who are infinitely better at what they do than the criticizers- know what it is....)
And - talking of quality v quantity - here's another question (especially for Chrispy) - how many bouncing frogs does a post have to contain before someone notices that you exist....?
Answer (especially for Chrispy) - none if you have something useful and intelligent to say......
