Jedef you make some valid points that would be worth of serious discussion - that is not going to happen. ;)
It is a game after all, and it is just that really. We must accept that some people just have more inclination to things such as these, that's all.
For example I sometimes get frustrated by my own game with my inability to play consistently, and then I think that I probably will never play consistently because I haven't got hours and hours everyday to practice and play as I have a family and a job to care for.
If most players score 50 or 39 over an 18 round, good, I don't think they are cheats nor I admire them, they just can do that.
Get my point?
Of course some players that score in that range will get offended by comments of cheating etc., this is because they are proud of that and become protective of their achievements on this game, I understand that, it is in the gamers personality.
I am in a CC, for example, and I have seen a player going from hack to very low average TM scoring amazing rounds in 2 and half months. I don't know how long I have been here but even in another 3 years I would not be able to score those rounds. I find that amazing. But of course this person is not cheating, he is just gifted.
