Chaos mode maps are really random from what I observed through discord chat, but I think the Chaos mode frequency itself is about 2-3 times occurrence every 10 Expert runs. We don't put anything that isn't from the official source or might be disputable, so I don't think we should include that unless you've found a calculation for that.

For Chaos mode enemy patterns, we'll be following JP wiki's format since they have compiled most of the info there.
