The point is that in real tennis, players don't aim for the baseline itself either. They try to hit deep with some safety margin; actually aiming at the line would mean taking a huge and usually pointless risk of hitting long.
TE4 follows the same logic: there isn't a "depth aiming" control where you directly tell your player "land the ball 20 cm from the baseline". Instead, the depth comes from how you play the shot.
As explained in the documentation ( =>
https://www.managames.com/tennis/doc/Te ... html#depth ), for non-short strikes :
- preparing earlier makes the ball go deeper
- good positioning and centering prevent the shot from becoming shorter
- higher Consistency increases depth
- standing closer to or inside the baseline usually makes your shots deeper
So the depth isn't pure random at all ; you can actively influence it, just not by directly selecting a landing distance.
Also, a badly positioned shot occasionally landing on the baseline doesn't mean bad positioning produces a "better" shot. It just means an inaccurate shot can occasionally end up extremely deep, exactly like in real tennis ; it can also end up too short or out.
So adding a dedicated "Deep" shot would actually introduce a new artificial depth-control mechanism rather than reproduce something that is missing from real tennis.
If you want to get more often long (and short) balls on well-prepared strikes, you can also switch to the Elite controls.
