Hi - anyone know an answer to this?

Search Analytics Report in SC shows Clicks and Impressions for selected dates. Then I download the Queries list underneath and the number of clicks and impressions is less than that in the summary numbers at the top of the page.

Shouldn't these two sets of figures match each other?

Reason I'm asking is Impressions has jumped in last 7 days by 10% and I'm trying to work out where the extra impressions are coming from. How accurate is that report do you think? In fact, if I download the report and do a calculation on difference between impressions from week 1 to 2, the difference is not 10% its much less.

Thanks in advance.
