The window
The protected time in which maintenance happens.

What it is
A window has to be in the production plan rather than in the maintenance plan, or it does not exist as far as scheduling is concerned.
Recording how often the window is surrendered is what makes the pattern visible to whoever keeps surrendering it.

Protected
Whether the window is in the production plan or only in the maintenance plan.

How often it is honoured, which is the honest measure of the schedule.
