Everybody,
I did a little mini-blog post to get an idea of the strike depth & speed in TE4 :
viewtopic.php?p=267234#p267234 .
Also, so far I didn't work on TE4 gameplay at all.
Currently TE4 is the new ball physics, new strike physics, new player physics, all tuned to give realistic CPU vs CPU matches. So changes will come for the human gameplay.
honestreview1) It's not a sweet spot thing, but the animation which isn't perfectly synced (do a slowmotion to check that). I already noticed that and I'll look why it happens when I'll be working on the gameplay.
And overall, the sweet spot is currently 3~5cm off because of the extra reach of the player brought by his wider chest.

I'll have to recalculate it once I'm sure the player is final.
4) TE2013 ball physics wasn't perfect for many many aspects, especially for the imprecision rules which were not physics-based but 2D based, plus the never-hit-the-net-except-on-big-fault rule. Both lead to many players complaining about these irrealistic aspects of TE2013.
5) The acceleration is already somewhat less forgiving than in TE2013.
The normal shot speed is more or less realistic.
6) If you aim left, and then aim right, the aiming cursor will immediately be on the right side of the opposing court, like if you had just started to aim right.
And in real tennis, you don't aim for the baseline.

CPU vs CPU matches give realist rally length average (or 15% above). For human vs CPU matches, I'm not sure as I still didn't play.
And what's wrong with the ball physics ? Or did you mean the strike physics ?
