Report Averages on a Number of Surfaces
When creating surface average reports the number of surfaces requested will depend upon the number used in the previous report. For example, if a report is created using 5 surfaces then these surface id's will be used for the generation of the next report. However, if the next report is only to use 3 surfaces then there is no apparent way to ignore the additional two faces from the previous report.
The way to get round this is to type ( ) after the identifiers that are to be ignored.
