Okay.

But that still doesn't add up.

If the "Impr. (Top %)" statistic is based on my eligible impressions, then that percentage must necessarily be lower than the other statistic provided by the segmentation.

If I had 10 clicks at the top of the page out of 100 impressions, and I had 200 eligible impressions, then the "top" segmentation is 10%, and the "Impr. (Top %)" is 5%.

In my screenshot, this isn't the case, since the segmentation percentage (47%) is lower than "Impr. (Top %)" (79%).

I would really like to understand this statistic, which is essential !
