I have not found the comment "Users can delegate reviewer (read-only), author (read/write), or editor (read-write-delete) rights to any combination of the calendar, contacts, Inbox, or task list" to be correct. I understood that to mean that if the owner delegates just calendar access rights to my user account that I can query their calendar. However this doesn't appear to be the case. The user had to delegate both calendar access and inbox access to my user account before I was able query just their calendar events.
