So the fix is in. I thought so.
Kidding. The 4,5,6 ... 7,8 deal is done ''randomly''. Seriously, after 1 and 2 are placed, then 3 and 4 are placed randomly either at the top of the second qtr or the bottom of the third qtr. Then 5 - 8 are placed randomly at the tops and bottom of the sixteenths. The 9-16 are placed similarly.
Check it out on just about any related website. Or go play a tournament with fairly large draws and ask the director.
It is very difficult to me to believe that such important things are left to "random". And if it is "random" then we have a repeated coincidence. Thrice in a row. Work out the odds. Let's say however that i stick by your story. Now, how would you explain the following:
Federer's draw up until 1/8 final: Qualifier, Qualifier, Qualifier, Qualifier, Qualifier, Qualifier, Isner, Nieminen.
Nadal's draw up until 1/8 final: Jones, Sweeting, Tipsarevic, Hernandez, Tsonga, Henman, Tursunov.
Do these fields of players seem to you as rather equal, or even slightly favorable for the golden boy, reflecting his status as number 1 compared to Nadal's place in number 2?
Or is there a huge difference?
And now look at Djokovic's draw up until 1/8 final: Ancic (CRO! 1st Round), Stepanek, Berlocq, Mahut, Del Potro, Hartfield, Melzer.
And what about this draw? Is it a fair draw for number 3 when number 1 is given such a royal treatment? Not even one qualifier for Federer's rivals?
Is all this again a "random" coincidence?
Some may say these are early matches so it won't matter. I would reply that in a grand slam a player must go in two weeks through seven matches of five sets. Everything does make a difference. That's why a player's total court spend time in the latter stages is considered an important statistical figure.
