General Performance Index©
(GPI: General Performance Index): "It is an index that measures the performance that a tennis 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 corre-spond to the month of January, have been included for the determination of the Top 30 of the General Performance Ranking©:

•    ATP Cup (Hard)
•    Qatar ExxonMobil Open – ATP 250 (Hard)
•    Adelaide International – ATP 250 (Hard)
•    ASB Classic – ATP 250 (Hard).
•    Australian Open – Grand Slam (Hard)

The ATP Ranking of the players, which has been considered for this report, is on February 3rd, 2020.

The 147 players who have participated in those 5 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.

We highlight the November podium formed by Novak Djokovic (SRB), Andrey Rublev (RUS) and Rafael Nadal (ESP), in positions 1, 2 and 3 of the GPI Ranking©, respectively.

Other prominent players in the TOP 10 of the GPI Ranking© are: Bautista Agut (ESP), Dominic Thiem (AUT), Daniel Ev-ans (GBR), Dusan Lajovic (SRB), Daniil Medvedev (RUS), Benoit Paire (FRA), and Karen Khachanov (RUS).

From reading the 12 tables presented in this report, there is absolutely no doubt that Novak Djokovic is more No. 1 than ever. The Serbian performance has been brilliant in all aspects. Djokovic has been, this January, the player who has best served, returned, has won all the matches and tiebreaks that he played. Andrey Rublev and Rafael Nadal have been his escorts in most of the tables in this report. Rafael Nadal continues, at the beginning of this season, demonstrating his usual performance regularity since the 2019 season (GPI Ranking©4).

Regarding Roger Federer, he ranks the GPI Ranking© No. 26, this January. Keep in mind that the Swiss did not participate in the ATP Cup or the other ATP 250. Federer only showed up to compete in the Australian Open falling defeated in the semifinals by Novak Djokovic in 3 sets, 6 (1) -7, 4-6 and 3-6. Although Federer won 5 of 6 matches, he only achieved the No. 26 of the GPI Ranking©, which shows us how competitive tennis is today.

It must be remembered that the statistical calculation of the indexes to make the GPI Ranking© takes into account, in a priority way, the “number of matches played in the period under analysis”, that is, the player who has played the most matches is because, in general, he has performed more satisfactorily. This explanation is for new readers who read these reports.

This aspect, I have already commented it on previous deliveries.
