Like the Central Market on a Friday.Its so the clubs can be more precise with their list management.
Rather than have to delist everyone and list everyone all in one go which is a relatively blunt instrument, you can delist some, take say one on, wait, have a look at what others did and see who's around, then chop again, or not, depending on what you think you have/can get, maybe add another on, etc, etc.







.....that's like the Captain of the Titanic saying " hey, don't look at me, it's not my fault"
