@jonas Not sure I understand answer re: 2. I would either expect value 1-10 where value 3 would represent 1,5 stars and value 5 2,5 stars etc or 1-5 where 1,5 would represend 1,5 stars and 2,5 would represent 2,5 stars. But apparently this is not how this works.

Sadly I have no second software to verify the current values are read correctly.
