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 build the "General Performance Index Ranking© or GPI Ranking© ".

This index considers, for its calculation, a number of aspects such as the number of played matches and won, the serves, the points won with the serves, the returns, the break points (saved and won) and the tiebreaks. Once the indexes are calculated for a given period of time, the 2021 season in this case, these indexes are sorted from the highest to the lowest and a ranking is established. This ranking is the General Performance Index Ranking© or GPI Ranking©, which is used to order players by perfor-mance in the analyzed season. As already mentioned in other articles, the ATP Ranking must not necessarily coincide with the General Performance Index Ranking©, in fact, this rarely happens. This General Performance Index Ranking© is very useful because it allows analyzing and quantifying the performance of an athlete in relation to the other players over a period of time.

The best performance of the season has been achieved by the Russian Daniil Medvedev (RUS), making him the No. 1 in the General Performance Index Ranking© or GPI Ranking© of the 2021 season. The GPI Ranking© podium is completed by Alexander Zverev (GER) and Andrey Rublev (RUS).
