First of all, extra big up for all this work. Especially, physics is very interesting in TE4 compared to TE2013. For instance, I very like the fact that players who shot the ball very "flat" (without lift) have a way bigger chance that ball goes in the net.

I just have some questions/suggestions.
1. When starting a pro career, there is a junior skill cap at 40%; is it a normal thing?
2. I found that speed of forehand and backhand are OK, but serve speed is a bit too fast imho. I know you must be able to range serve speed up to the real maximum, that is around 230 kph, but it is maybe too "easy" and not very real that every top player are close from these values. So here are some suggestions. The first is: top players like Nadal, Federer or Djokovic are over 90% serve speed, but in fact rarely serve over 210kph in reality; I think it wouldn't be a shame if players over 90% of serve speed are rare and include only players that really serve very fastly (for recent times, there are for instance Raonic, Karlovic, Isner...). The second is to reduce the max serve speed at 100% but add a talent of "very fast serve", to be able to serve faster than the 100%. The third would be to range skills as in multi also for IA players in career, or at least, with a maximum of 90% of skills. I usually save players from the "pick real player" career menu to train against them. I usually play pro 10, but I have either to lower their serve speed to have a real opposition (otherwise they do 4 aces and we play only on my service) and nice rallies, or play lower than 10, say 5 or 2, but I won too "easily".
3. When you are hitting a ball, there is an optimal distance to shot it from the body of the player. I was wondering if, when we have different shot styles, this distance varies. For instance, I find it very natural and easy to do great shots with Nadal forehand style, but really difficult to accelerate without going in the net with Del Potro or Davydenko, whose forehand style is with the racquet going further I think. So is there a difference between shot styles regarding the optimal distance to hit the ball?
4. I didn't know if you improved the volley physics, but I found it (for now) a bit too much like that of TE2013. I think the key point is the reactivity of the player, which can be optimised I think. And maybe add some extra buttons to be able to control if the player plays it with the forehand or the backhand? Many times, I want to slide to one side to play the ball, but the player doesn't do what I want ^^, say for instance I'm a right, and I slide to the right to takes it with backhand, but the player automatically takes it with the forehand and it finished in the net. See whet I mean? I think I'm not the first to complain about this, it makes me sometimes angry when I want to play more with volleys ^^
5. Maybe add more shot styles or more variation depending on if the player is static or hitting the ball when running. This suggestion is only to be visually even closer to the reality, it is less important than game mechanics suggestions; in other tennis games, there may be that kind of animations but their physics are so bad that we just can't consider playing them
You really do a great job anyway, I spent hours on TE2013 and I will spent even more on TE4 for sure! These comments are for maybe improving the game even more, it is already very enjoyable as it is
