It's kinda hard to call it an "ability" when it's something that was coded in from the start. They're not programmed to make mistakes, they're programmed for perfection.

Lemme put it this way. I could train for years on how to draw a perfect circle. And maybe I'd get it once or twice, but being human, I'd make mistakes. Androids all get it right on the first try. They don't gotta train or hope they'll do it right -- they just do.
