I'm trying to calculate tennis players progress/advancement of several last games by using only scores of the games. For example - progress of the 5 last games:
- 5-7, 4-6
- 4-6, 6-4, 4-7
- 6-4, 4-6, 6-2
- 6-2, 6-0
- 6-1, 6-2
Looking at the scores we can see that a player is in a good progress, but how to calculate it in percentage? Atleast progress percentage from one game to another, not all at once.
Can somebody help me with formula? I need ideas. Thank you for your time :)
