35:33 The Rankings resulting from the ‘Dominance Index’
► Part no. 1: from August 23,
1973 till
December 31,
2015 only 25 tennis players have reached the #1 position in
ATP Rankings from Nastase (1) to Djokovic (25).
Only 4 players have been #1 for more than
200 weeks: Connors (268), Lendl (270),
Sampras (
286) &
Federer (302).
► Part no. 2: in my opinion can be distinguished the following 5 different periods:
❶ A first period (August 23, 1973 - July 29 ,
1974) that I call ‘The
Beginnings’: it lasts very little (Nastase and Newcombe in less than a year).
❷ A second period (July 29, 1974 -
September 12,
1988 = over 14 years) in which there are only four new #1, in order: Connors, Borg, McEnroe and Lendl. It is a period ‘blocked’ by these four great champions. I call this second period ‘The
BIG 4’.
❸ The third period (September 12, 1988 - March 30,
1998) shows seven new #1 in about 9.5 years, in order:
Wilander,
Edberg,
Becker,
Courier, Sampras, Agassi and Muster. It is a period a little more dynamic. I call this period ‘Sampras & Agassi’.
❹ The fourth period (March 30, 1998 -
February 2, 2004) sees the appearance of nine new #1 in less than six years. Jokingly I call this period ‘
The Wild Bunch’ (remembering the movie by Sam Peckimpah,
1969).
❺ The fifth period (February 2, 2004 - December 31, 2015) sees a situation very similar to that previously called ‘The BIG 4’, with three big rulers (Federer,
Nadal and Djokovic) in nearly 12 years. I call ‘The BIG 3’ this last period.
► Part no. 3: Precocity. The analysis of earliness shows that the greater precocity belongs to Hewitt and
Safin (less than 21 years old), while the lower is of Newcombe (30 years), who was catapulted (as Nastase) into the ATP Rankings when his career was already fully developed.
Longevity. The analysis of longevity with which each of the 25 champions has maintained or regained the top spot of the ATP Rankings shows that the highest longevity belongs to Agassi and Federer (over than 31 years old), while the lowest belongs to Safin and Roddick (less than 22 years old).
Duration.
Let’s analyze the time elapsed between the first and the last day in position #1 of each of the 25 champions. The more extended duration belongs to Connors, Federer and Agassi (over 8 years), while the lower belongs to
Rafter (only one week).
► Part no. 4: let’s compare for every player the following two elements:
a) the number of weeks at # 1 and b) the duration (years) between the first and the last day at #1.
The resulting
Matrix may be represented in a two-dimensional plane, displaying the data combination of two elements:
- on the horizontal axis the number of weeks at #1;
- on the vertical axis the duration (years) between the first and the last day at #1.
► Part no. 5: I added the wins obtained by the 25 champions in
Grand Slam Tournaments.
I also added a 26th player, Vilas, who conquered 4 slams; some discussions are ongoing about whether Vilas got or not got first position in
1975 or in
1977.
I then calculated - for each of the 26 champions - the 'Dominance Index'.
★ Federer is in the first position in the Ranking based on the 'Dominance Index'.
Sampras is in second place, Connors is in third position. Nadal is at 4th place, Djokovic at 7th.
The great rivals McEnroe and Borg (8th and 9th place respectively) are almost matched, as well as Lendl and Agassi (at 5th and 6th place respectively) and Edberg and Becker (at 10th and 11th place respectively).
Note that the BIG3 (Federer, Djokovic and Nadal), being still active, in the coming years will be able to improve their own scores.
★
At the end of each of the next years will be interesting to see the changes that there will be in this special ranking, as a result of:
- the performances that players still active will obtain year by year, starting in 2016,
- the new "stars" that surely (sooner or later) will appear in the firmament of the tennis world and will occupy the top spots in the
ATP Ranking.
