I have a carpet tournament next week and i'm just curious
That ball is not going to bounce at all. All I can say is good luck and that match is going to suck to play.
Compared to hard courts, carpet courts will cause the balls to bounce lower. This is because the carpet surface is more foregiving, i.e. softer, which absorbs the energy from the ball. I'd say it plays most closely to grass. Due to the friction of the surface, spins have a greater effect, eg. skidding slices. Soft and great for the joints though. The speed of the surface is dependent on the makeup material and thickness of the carpet, but usually pretty fast. Is this tournament indoors? Have you played indoors before? There are those factors to consider as well, such as ventilation (for breathing), ceiling height (b/c if you hit it, you lose the point), and echo (from hitting the ball). All those factors are worth considering as well. Good luck!
