Review comment:
       It was not strictly necessarym but it increases the readability IMHO. It shortens the name but it also increases the mental effort to look up TI and DR elsewhere. I think the code is much more readable when you explicitly spell the class that you use rather than use shorter, two letter names. This is the same reason why pylint disallows short variable names and prefers longer alternatives that spell the actual variable name (df/dtm/fn etc.). That's why I put it as the same change.
   
   In general the code IMHO should be optimised for being more readable explicitely then shorter-writeable.
