It takes time to learn.
First of all the correct Numismatic terminology is Doubled Die.. not double die. It's important to know that.

Strike doubling such as MD - Mechanical or Machine doubling known as Worthless doubling is not a variety and explained here - https://doubleddie.com/144822.html
DDD - Die Deterioration doubling is also Worthless doubling is not a variety and is explained here - https://doubleddie.com/144843.html
