List Import

I believe that only Travis Bell can clarify all items.

When I Export any list from TMDb (Rating, Watchlist and Favourites) I see the same header line in the .CSV :

Rating      =   TMDb ID,IMDb ID,Type,Name,Release Date,Season Number,Episode Number,Rating,Your Rating,Date Rated  
Watchlist   =   TMDb ID,IMDb ID,Type,Name,Release Date,Season Number,Episode Number,Rating,Your Rating,Date Rated  
Favourites  =   TMDb ID,IMDb ID,Type,Name,Release Date,Season Number,Episode Number,Rating,Your Rating,Date Rated  

I assume for Watchlist and Favorites the Date Rated field is actually the Date Added field.
1 Am I right ?

In addition, when Importing a list to TMDb, I believe that only data from the following fields are imported.

IMDb ID,Type,Date Rated,Your Rating,Season Number,Episode Number  

2 Am I right ?

Required for Any List: IMDb ID, Type
Useful for Any List: Date Rated
Required for Rating List only: Your Rating
Required when applicable for TV: Season Number , Episode Number

3 Am I right ?

4 Are any other fields read in the import ? For example the Position or Date Added field ?
5 In the .CSV file for Import, can the order of the fields, the sequence, be changed ?
6 Can the fields that are not read, in the current 3 of IMDB, be deleted, including deleted from the header ?
