General Performance Index©
(GPI: General Performance Index): "It is an in-dex that measures the performance that a ten-nis player has had in a given period of time." This index, not shown here, is used to make the "General Performance Ranking© or GPI Ranking© ".
The following tournaments, which correspond to the month of July, have been included for the determination of the Top 30 of the General Performance Ranking©:

  • Wimbledon – Grand Slam (grass).
  • Hall of Fame – ATP 250 (grass).
  • Swedish Open – ATP 250 (red clay).
  • Plava Laguna Croatia Open Umag – ATP 250 (red clay).
  • Hamburg European Open – ATP 500 (red clay).
  • BB&T Atlanta Open – ATP 250 (hard, SportMaster).
  • J. Safra Sarasin Swiss Open – ATP 250 (red clay).
  • Generali Open – ATP 250 (red clay).
  • Abierto Mexicano de Tenis Mifel – ATP 250 (hard, Solflex).
  • Citi Open – ATP 500 (hard, SportMaster).

The ATP Ranking of the players, which has been considered for this report, is on August 5th, 2019.
The 184 players who have participated in those 10 tournaments and who compound the statistic sample that has been considered for the statistical calculations, we reiterate, only the 30 with the best performance are exposed in this report.
Remember, performance that is totally inde-pendent of the ATP Ranking. For example, Novak Djokovic (1) and Roger Federer (3), whom despite having reached the Wimbledon final, they only played this tournament in the period under analysis, which includes 10 tour-naments. A player cannot claim to achieve ex-cellent performance in this period, if he has played only one of the ten tournaments, even though he holds No. 1 or 3 of the ATP Rank-ing. This the reason that we calculate the General Performance Ranking© or GPI Ranking© to make a performance ranking that highlights the work done by players despite they do not have an outstanding ATP Ranking, but who have performed brilliantly during the analysis period. That is the case of Albert Ra-mos-Vinolas, whom has been the best player from the point of view of his performance in this period with his ATP Ranking 52 despite of he has not had the press or marketing that would have corresponded. The tennis fans and the press keep an eye on the Top 10 or the new stars, but there is a legion of players that from the point of view of the ATP Ranking do not stand out (there is an explanation for this) but they have a very good performance (see table 1).
According to table 1, only 4 Top 10 of the ATP Ranking are listed in the Top 30 of the GPI Ranking©. These are, Novak Djokovic (1), Roger Federer (3), Dominic Thiem (4) and Daniil Medvedev (9). Rafael Nadal, who was the best performer player in the second quar-terly (see article No. 89: April-May-June), in this report No. 91, he is not included in the Top 30 of GPI Ranking©, his GPI Ranking© has been 39 in this period of tournaments that be-gan in July.
If someone wins an important tournament and then goes on vacation to the Caribbean or an-other place, he cannot pretend to have a good performance. My statistical calculation system does not consider if someone is No, 1 of the ATP Ranking, if is Djokovic, Federer, Nadal, etc., simply all tournaments have the same im-portance, and the same happens with the players. Therefore, if someone in the analysis period played 1 of 10 tournaments, no matter if he won it, the performance of the period for that player will consider that he did not play the other 9 tournaments and his performance will be conditioned by that situation. For that rea-son, Djokovic (1) for example, has a GPI Ranking© of 22 in table 1 and Ramos-Vinolas (52)has a GPI Ranking© 1, who is the best ofthe period. In parentheses, the ATP Ranking,August 5th, 2019.
We highlight the July podium formed by Albert Ramos-Vinolas (ESP), Joao Sousa (POR) and Taylor Fritz (USA), in positions 1, 2 and 3 of the GPI Ranking©, respectively. Other prominent players in the TOP 10 of the GPI Ranking© are: Jeremy Chardy (4), An-drey Rublev (5), Juan Ignacio Londero (6), Ugo Humbert (7), Roberto Bautista Agut (8), Reilly Opelka (9) and Guido Pella (10). As can be seen, in the previous paragraphs (see Table 1), none of the players that are part of the Top 10 of the General Performance Ranking© of the month of July are Top 10 of the ATP Ranking, the same situation hap-pened in the previous month of June. In addi-tion, only 4 Top 10 of the ATP Ranking are included in the Top 30 of the GPI Ranking©, namely Dominic Thiem (19), Novak Djokovic (22), Daniil Medvedev (23) and Roger Federer (24). Moreover, only 13 play-ers Top 30 of the ATP Ranking are included in the Top 30 of the GPI Ranking© (See table 2 for verification). It is interesting to take a look at table 3, where the relationship of the won matches over the total played matches in the 10 tournaments covered in this report are exposed. This table 3 is led by Novak Djokovic, with a ratio of 100% of won matches over total played matches (7/7). He is followed by Nick Kyrgios (87.5%) and Roger Federer (85.7%). In this table 4, only 4 Top 10 of the ATP Ranking are listed, and they are the same that were men-tioned above in table 2. Next, the tables with their respective perfor-mance rankings or GPI Ranking© are ex-posed as is usual, in each analyzed aspect of the 30 players that achieved the highest per-formances during the analysis period. Remember, each table presented here has its own GPI Ranking©, which they are combined together and gives as output the table 1.
