What is crowning in timber floors?

From a professional specification perspective:

Crowning appears when floors become wet, cup, and are then sanded prematurely before moisture has balanced through the boards. This creates a surface where the centre of each board is higher than the edges -- the opposite of cupping. Floor Sanding Australia warns that sanding cupped floors before moisture has stabilised leads to permanent crowning.
