Without getting into much detail, playing and watch tennis is as different as night and day. It may look simple enough to decipher, but trust me, this is one of the deepest sports out there. You are not even swimming in shallow waters, you simply stepped into a tiny puddle of water when it comes to your knowledge. I have been playing and coaching foreclose to 20 years now and I learn something new every day. My intent WAS to get you (as you put), because when talk realistic, and explain your reasons why - you are so off base that one can think you are playing some other game, not tennis. So if I were you , I would stick to the game, cheese, etc... and avoid real life compassing, as you are simply don't know what "real life is".
I understand that you don't care much about TS4, since you from day one didn't like it or after the first week(I don't know). Still, if you play the game, the representation of tennis is very adequate as to what you see on TV, youtube, and all other medias. However, yes, it doesn't play like "REAL LIFE" tennis. Way to many details taken away from the game to simplify (sadly) the experience. Though, look at the games representation, it isn't way off watching a tennis match on tv, don't misinterpret what I mean, it is way off, considering all details and all variables of real life tennis, however, the basic elements are more than recognizable, and you sure get a feel of tv-tennis in the game. Which is why so many people play it.
You are right, I haven't played any real competitions. However, you are wrong. I do play tennis in real life. I've played actively for 2 years, and are learning pretty fast. I'm already rallying at the level of people who have played the game for 5+ years. My service is still quite inconsistent. I have a decent forehand as my best weapon. I play single handed backhand. I have very good balance in my upper body and my backhand is my technically best stroke, (according to my coach and other coaches at my club) however, I'm not hitting many winners with it(Lack control when using more power). I'm able to put quite a lot of spin on my shots if I want to. (One of my sparring partners, which have played for 4-5 years and is one of the best girls under 25 in my club and region, have complained about exhausting topspin shots from me) I consider that I'm mentally relatively weak in match situations. Have only played 6 singles matches yet in my career though, all 6 in my clubs annual championship this year. Won 2 out of the 6 matches. Whereas, I played against a guy, that I know I can beat, if I play my best, however, I have to have a good day too. Anyways, in my match against him I was one break up in the first set, and I just couldn't control my nerves
He then broke back and won the match. 4-6, 2-6. Overall, I feel like I have a lot of potential yet to be discovered before I "hit the wall" and the learning slows down. 
I follow all posts, I like the reading and the interaction. I like arguing too. What I don't like is when people "deflect" when confronted with facts and when their "facts" are shown to be just "personal agendas". I admire your "never give up" spirit and this constant flow of positive energy, but I don't like the fact that when you are put in the corner, you don't acknowledged that and instead, find something else and completely forget that just a few days ago you were "way off base" of a similar subject, proclaiming that "this time" - THIS IS IT.
I'm sorry for the deflecting against Tam. That was meant as a joke towards him. He mentioned that I already answered like a president(answering questions with questions), I then thought it'll be fun to do that for a couple of posts. I didn't realize that he got really fed up about it, instead of thinking it was funny. I try not to deflect anything. I think my opinion about R1 serves makes sense in TS4. To me it adds to the excitement of trying to read what your opponent is going to do next. Dennie also uses r1 serves (or at least he did, don't remember what he did in our latest matches) , and in my matches against him, I think it's exciting to try to get into his head, knowing when he wants to go for S&V and when he stays at the baseline. It's too easy to return well in TS4 (compared to watching tennis on TV), which is why it would be silly to be locked to going all the way to the net, when using S&V modifier. If you know that your opponent have to go to the net when using r1-serve, you can adjust your return to the returns that are most efficient against s&v(deep topspin down the line, short topspin cross court, short slice, or short power flats that travel low over the net.) However, if this is the simplest thing to read in real life(s&v or not), then sure, I'll stop using it.
It reminds me of a McDonald's commercial, where they say: "...now with REAL meat!" - so WTF where you selling before that?!
For me, it's a science-project kind of thing. Where I'm testing different hypothesis and often doesn't test them at all, just post them in thread and see what everyone here thinks. It's ideas that I think could be interesting to try out and my latest thing is the one idea, that after testing it, makes this game play much more like the tennis shown to us on TV. (No impossible flat short crosses and no slow flat floaters that land on the lines every single time.) Personally, I never get the feeling of playing "real tennis" in this game. I just really enjoy the feel of tv-tennis this game gives.
No joke. The way you interact is almost identical. Granted, you more "there" then he was, but the resemblance is there.
You can relax though, I'm not Q.
