I am pretty sure, that I have not suggested to use an import text file, which is formatted in columns.
I am pretty sure, that each character on a line, within the import text file, is significant for the Mp3tag import function.
Therefore it is not good, to offer data columns, because the possible imported trailing spaces have to be removed afterwards from the tag-fields.
(Annotation: Your preview picture shows, that Mp3tag seems to understand the data, which have been formatted in columns, but the formatstring for importing looks ugly.)
The import text file should have left aligned floating lines of text with unique separator between the data fields.
In Mp3tag you can choose the separator character or string as you wish, but it should not be part of any data field.
In your case you can offer a text import file:
|-1|C:\temp\media file 1.wma|
|0|C:\temp\media file 2.wma|
|20|C:\temp\media file 3.wma|
|40|C:\temp\media file 4.wma|
|60|C:\temp\media file 5.wma|
|80|C:\temp\media file 6.wma|
|100|C:\temp\media file 7.wma|
Import mask:
|%RATING_XXX%|%_path%|

The problem to solve seems to be ...
... to align the numerical/star ratings from Rating_MM to WM/SharedUserRating
... to find the transfer formula between Rating_MM and WM/SharedUserRating.
Stars MM WM
0 0 0
1 1..23 1..24
2 24..64 25..49
3 65..128 50..74
4 129..196 75..98
5 197..252 99
--------------------------
If you could transfer the stars between the rating systems, then the problem is trivial.
