When you request percentages on a table of nets, Quantum calculates the percentages against the number of respondents in the base rather than on the number of responses in the net. If you want percentages based on net figures there are a number of things you can do.

The first option is to place the keyword base on the net element. This flags the net element as a base and percentages for all elements that come after this net will be calculated using the net figure as a base. For example:

Here the two level 1 nets are flagged as bases. This means that the percentage for favorable responses about the bottle will be calculated using the number of respondents making favorable comments of any sort as a base, rather than against the total number of respondents in the axis. The same is true for unfavorable comments where, for example, the percentage for the comment ‘Too big’ is calculated against the number of people making unfavorable comments.

Here is the table itself:

With this method you have percentages calculated against the net figures, but you have lost the percentages of the favorable and unfavorable comment nets against the table base.

An alternative is to create the table using op=126 and to place base on the net elements. With this method the net elements have percentages calculated against the table base, while other elements have two percentages, one calculated against the table base and the other calculated against the appropriate net.

A third choice is to define nonprinting base rows immediately after the net elements:

This gives you one percentage for each row. The net rows are percentaged against the table base and the other elements are percentaged against the preceding net:
