The way you're checking both the front and side plains in the level test, you're taking the deviation between the marks on the wall from the original laser position, and the laser position after relocating the laser, and dividing by the distance between the marks. But I don't think you're making it clear that for the side plain, this distance is between the marks on the same wall, and for the front plain, this distance is between marks on opposing walls. Or am I misunderstanding what you're doing?
