Here is the answer from the SDK page:
The documentation will be updated with a new range, from 0.2 to 1.2, keep in mind that this is a recommended range and the value could be way above/under it but it will lead to unrealistic behavior.
The C172sp value will also change, 4.3 is indeed a mistake and it will be corrected in a future update.
