As we know, automatically created statistics, as can be see with
SELECT * FROM sys.Stats WHERE object_id LIKE OBJECT_ID('MyTable')
(only change 'MyTable' for something else), has name starting with _WA_Sy_.
Were you ever curious what was that _WA_ for?
I heard yesterday that it is abbreviation for WASHINGTON, where MS SQL Development Team is residing.

It says that WA really stands for WASHINGTON
Yes it is specified here

Well. I did not see Olga Medvedeva's reply when I posted mine
