So his dad who doesn't even live in the same colony with him magically descended through his window one night waving top secret info about the major hope of the Earth Federation to develope own MS in front of his nose "hey Amuro it is good Operation V info YU MUST LERN NAO!". And your firm belief is the undeniable proof. And what the heck do you mean unevolved Char? Char was a Newtype to begin with. Amuro was the one that needed to awaken.
Amuro Ray was without a doubt one of the best Gundam pilots ever, however, he was evolved. He also was the son of the designer of the Gundam. I fimly believe, although the anime never states this, that he had some knoweldge of the inner machinations of the Gundam prior to using it. That's why he was able to do what he did right out of the gate, again this is speculation. His early career was standard. He was an ace, but yet still the unevolved Char was able to best him time and again. Plus he was a hot head. He would break protocol time and again. Heero was a machine. Goal. Accomplish. Goal. Accomplish. No room for error, no room for mistakes.
