Grading system
The algorithm used in the ranking system is called Elo/Glicko rating system, and official examples explain that it is similar to the ranking system designed for chess.
The ranking system starts from the first five games, and this is your skill score, which is mu variable in mathematical terms. This variable will be updated after each game.
Then this variable will be calculated differently in different matching areas (Asia is a variable in Asia, Europe is a variable in Europe, North America is a variable in North America, and so on). This means that it is not suitable to compare ranking results across regions. This is not an absolute value, but a value relative to different regions. To put it bluntly, the diamond level in North America may be very different from that in Asia.
