I don't think you can achieve perfection in a few years. Gai stated before he trained him, Lee had absolutely no talent not even in physical abilities. He was basically a 1 out of 20, with 20 being where he was in Chunin Exams. Sasuke was probably at a 10 and needed less training. Then Sasuke just copied his form from his fight. Sasuke took Lee's movement speed, Lee moved plenty against Sasuke. Then you have the possibility of Kakashi who could have copied some of Lee's form and showed it to Sasuke and Sasuke could've copied that. In fact, I think it was stated Kakashi did do this, but I could be wrong. All Sasuke had to do was train in Lee's perfected form, and produce results quicker than Lee since Lee spent years perfecting his art. He still is even as a Jonin. If you reach perfection then there is no reason to train.
