Protection levels are hierarchical and are from highest to lowest:
The levels are also inclusive. This means that a user with delete protection also has modify, access, and read privileges; a user with modify privileges does not have delete privileges but does have access and read privileges; and so on.
In general, the first user to request a protection level is granted it. Subsequent users requesting a protection level will be granted it only if that level accommodates multiple users at that level.
