Wait how does the computer system change what the race actually is? I thought Kyrptonians naturally had that stupid amount of abilities, only reason the race mostly died off was because they didn't train enough.
Sounds like you're mixing up Superman with Goku or...something. Because I don't think this has ever been a thing with Superman's background. I want to say originally it was said that Kryptionians were all as naturally as strong as Supes, but they quickly did away with the idea since obviously no race that naturally strong would all die out when their planet exploded.
Superman just instantly got his power when he came to Earth and got that yellow sun fix. He never trained to improve his power, just to get in control of said powers (such as what was portrayed in Man of Steel when he first gets the suit). He didn't train to get said powers unless they rectonned it at some point that he trained insanely hard on his spaceship as a toddler when he was flying through space, but that would be some next level DBZ shit right there.
