For the "Default" and the "Simple" forms, the weighting factors for each criterion (review category) can be set, too.
Please go to:
Overview => Settings => Review Form Options and Factors
... to set the weighting factors for each criterion. You can also disable criteria here.
Please note that we do not recommend setting the "Overall recommendation" to 0%, as this might be confusing or lead to (logically) inconsistent review results. If you click on "Edit Phrase", you can edit the wordings of each criterion (see image below).
If you do any updates, please test them!
