When you perform a biofeedback scan or a grade program operation, the list you get back will be ranked from highest to lowest based on the operation in use.
Max BPM - Highest to lowest in terms of beats per minute.
Min BPM - Lowest to least lowest in terms of beats per minute.
Max HRV - Highest to lowest in terms of maximum heart rate variance. Remember this is an absolute function, so it could be either that your response was a spike (stressor) or a rapid decrease (calming).
Min HRV - Lowest to least lowest in terms of heart rate variance -- little change was recorded from your average heart rate response.
When comparing the result sets if you are not going to keep the entire set (remember those hits were already filtered out of all frequencies tested), then you could use statistical methods to trim.
