After a game, a player is given or removed skill points based on how well they played compared to the computer's skill level, though some games do not calculate points during multiplayer sessions. The game keeps track of points by putting them on a graph, as well as making a bigger crowd in Tennis and Boxing single-player modes. After getting 1000 skill points in a sport, a player is get "pro" level, along with a new feature for their Mii in Bowling and Boxing. A Mii newly turned pro will get a message on the Wii Message Board to tell them. "Wii Sports" also has a fitness test that calculates a player's fitness age (from 20 to 80 years old, 20 being the best possible). The test uses the player's performance in three randomly chosen challenges in each test from the training mode, and can only be taken once a day per Mii. Fitness age takes into account a player's balance, speed, and stamina. Fitness age results are graphed over one, two, or three months, with daily results on the Wii Message Board.
