could you help me with this problem?

#1
In the month of May a tennis player A reached the maximum odd of 4 every 3 matches he makes against other players who usually statistically reached in the same month the maximum odd of 3 every 3 matches..
In june the same tennis A reaches the maximum odd of 4 every 6 matches he makes against players that usually reach the odd of 3 every 3 matches they make
(so things changed a little better for tennis A)
How can I calculate the probability that the tennis player A when playing with tennis players who make the maximum maximum the odd of 3 every 3 matches, can reach himself the maximum odd of 4 when he's going to play a match with a tennis player who reach the maximum odd of 3 every e matches they make?
If I wanted to put all those data into a statistical program like R, what should I do? What should I calculate? How could I do?
