I got your Bug Reports, so in short, there's nothing wrong nor unusual...

1 >> I think this return would be different in the previous version...
The ball difficulty was very low.
2 >> Another centered return where i aimed to the line
You aimed 2 meters away from the center and with the aiming zone still being big, the ball ended on the center of the T.
3 >> Here my opponent played a centered return
He was misplaced so he stopped to prepare his strike to move more, then he prepared it again but way too late and thus aimed near the center.
4 >> Centered return... it happens very very often now
Almost same as 2 >> .
5 >> This whole game was played in the previous update and it shows perfectly how different the returns were in this update (and im behind the baseline in both)
You replayed that older .dmo with the latest version, so if there was the slightest difference in the gameplay, this would create a desync and the point would not replay correctly (usually this lead to the players moving in the wrong direction, the point given to the wrong player, etc.).
This actually shows that (almost) nothing changed...
