Why are there discrepancies in my data segment report?

In some cases, the Data Segment Report may add up to more impressions than the campaign won. Since multiple audiences and contextual segments can be targeted using boolean logic, multiple segments can match for a single impression. In this case, the impressions are counted in the row for every segment that was used to win the impressions. Therefore, each segment will show all of the impressions it helped to win, regardless of whether multiple segments were used to win the impressions. 

For example, "Male" AND "Sports":

If you won 100 impressions using the segments "Male" AND "Sports", the report will show 100 impressions won for Male, and 100 impressions won for Sports. Although these segments will add up to 200 impressions, the actual number of impressions won will be 100 impressions, as both segments were used to win all impressions.

In other cases, you may see excluded segments shown in a Data Segment Report. The report contains a row for each matching audience/contextual target. 

For example, "Sports" OR "Entertainment" AND NOT "Finance":

In this scenario, "NOT Finance" will match every time an impression is won. Therefore, a row exists in the report for this, which may appear as though you have bought impressions with the segment "Finance". You may have won 100 impressions that matched the "NOT Finance" rule, and also 50 that match "Sports" and 50 that match "Entertainment". No impressions were won because they had the Finance segment, rather 100 impressions were won because they were NOT Finance, in addition to the other targeting.
