Anyone know latest "patterns" for least-busy days in each park?

[Sharper]

In the past, there were some traffic patterns for the parks which could help in planning which day to go to (or avoid!) particular parks. (Like Monday being a busy day for MK, since many arrive on Sunday and kids want to go there first) With early admission being discontinued, and whatever other factors may come into play, is anyone aware of certain days which are less busy or particularly busy for individual parks?
