Today I've tried a little experiment and I'm a bit confused...
Hope someone can explain to me.
I've made a player 0-12-8 and selected the coach "Peto Chesire" who give to you Topspin invasion and poisoned slice, then I've played some matches. Later I've created another player with the coach "Pei Jing Quah" with Topspin invasion and monster defence (both players had FH almost the same included the bonus of the coach, just power was 3 point less on the first player)) and played some matches.
After that I've noticed that with the first player the topspin become really effective after 7-8 shots (all on FH)... with the second player, the topspin became effective after 2-3 shots (All on FH)! so the two topspin invasion are a bit different since the first one was not so powerfull.
it's just my impression or someone other have noticed this too?
maybe this setup has something hidden?
