talent is worth something?

I've been noticing lately (race after race) that drivers with the same ability in legendary but with different talent don't notice anything. In other words, whoever has more talent does not run more or have more rhythm... which leads me to think that either you have reduced the difference between pilots of different talents much more or having paid for two T30 academy pilots is one of the biggest scams I've seen in a current game.

I would like clarification.

Seeing your past results in the league, you have either become very good or you have gotten some kind of an edge, I wonder what it could be?
You do indeed gain an advantage, but perhaps your expectations of what a 30 talent should give are too high.
Strategy, car design, driver's fav track and race management doesn't become irrelevant, you still can beat a talent 30 with a talent 20.

So it is the latter. Having young T30 pilots is a good scam. 

And no, I didn't go from being slow in igp to fast.

Join a top league without a talent 30 and you'll clarify your doubts by yourself. 

Explain to me, if you please, where the difference is noticeable with a talento vs a non talent.

End of race? Qualifying? Curves? Push?

Everywhere. Literally everywhere.

Talent impacts a driver's speed, so a T30 driver is faster over a lap and race than an equally trained T20.
However as others said, this difference can be mitigated by better management, car design, strategy....

Have you ever tried not being so insufferable? I like that you ask questions but the way you phrase them is terrible and gets you short responses.

But also your questions are really bad sometimes. You have the worst quality of posts in the forums for as long as I can remember, even when I was the head of support here.

Always with calling something a scam.
