Is an "ad impression" the number of times an ad is run? Or is it per text ad? (i.e. 1 leaderboard = 4 ad impressions).
This clearly could have a major effect on interpreting data

I just broke a channel down into smaller channels for better ad tracking and it seems that even though it shows each channel having say 100 impressions, the total also comes to 100 impressions.
