This question I feel would be better answered by User:Emptylord as he was the one who designed that template. You'd perhaps be better answered by asking him.

Nonetheless, I am capable of answering your question: the value that you see the champion apparently gain 'per level' is not actually per level, but merely a number called the 'Growth' statistic that the actual level-up stats are derived from, using a very complicated formula.

I would assume that the template pulls the Growth stat from each champion's data page and calculates it on the fly. I haven't taken a peek at the code myself to verify that, though.
