filter for a snapshot in past 'in past xx days' combined with 'not in the past xx days'

Hi All,

I need to create a report that returns the amount of people with a lead status change for a time period in the past. Using the date picker is not ideal as this would be a manual process. I am trying to achieve this via 'in past xx days' combined with 'not in the past xx days'.

In this example, this would mean people whose lead status changed to re-marketing during the period 9 Dec to 16 Dec 2015.

Here is an example

I dont trust the results, would someone be able to test this logic and advise weather this is at all possible?

Thanks

Matt
