What is the T-CSR (Temporary CSR) and why is it now shown in games?

The T-CSR (Temporary CompuSport Rating) is your real-time, game-by-game rating in billiards. It changes after every game you play, reflecting your immediate performance.


While it is more volatile than the CSR, the T-CSR provides a quick snapshot of your current form. Your official CSR is then calculated as the average of your T-CSR over the last 12 weeks in which you played, giving a more balanced view of your skill level over time.

Why is T-CSR now shown in games?

When you view a game listing, the rating change shown is calculated using T-CSR because it captures your current form at the exact moment the match was played. Showing T-CSR in game listings makes the displayed rating consistent with the value that was used to compute the result.

Your official CSR remains the long-term reference used for division placement, handicaps, and event registration.
