In the China Open 2019, the statistics of the placement and the spin (rpm) were showed. It's my first time seeing these. So nice!
Any buddy can help answer my questions below? Thank you very much!
1. How did they get the figures? What kind of devices were used? Especially the spin one?
2. I couldn't see the same things in the competitions afterwards, like the Hong Kong Open, Japan Open. Did they do the statistics only in the China Open? Why?
