Being a noise level means you don’t notice. It doesn’t mean it doesn’t register.
If it’s small enough, it literally won’t register, but there’s more to that than just being small. If you get to the point where it registers, and move back epsilon, then all it takes is an epsilon difference. Unless you were very, very careful about how you chose your people, there’s going to be an unimaginable number who are within epsilon. Even if you made sure all the people were exactly identical, there’s still a chance that they’re all within epsilon.
