I mentioned this solecism (at least) once before, but I found a comic for it, so here’s a repeat.
The rule is that “per” means “according to,” and that’s all you need to say. Don’t use “as per”!!! Ever. Unless you’re telling someone not to use it.
Paul Trap does a good job of making Dad try to be formal, but managing only to be pretentious. Considering that’s he’s talking to an infant, the pretentiousness is even more out of place.
Remember, you want to write so your reader thinks about the subject, not about the writing.
