Email Open Decay Report in RCE

[Tim_Madel1]

Something seems broken with this report in my RCE.  When I first open it up the default time frame is 7 days.

I have an email sent on a Tuesday with open rate of over 67% on that Tuesday. 

If I change my time frame from showing emails sent in the past 7 days to emails sent in the past 14 days.  The email on the particular Tuesday seems to disappear.

How would extending the time frame affect the open rate of emails sent on a date included in the original time frame?

Are there a lot more sends in the last 14 days than the last 7?

No

It should not remove the email from the report.  Has anything else changed with the filter?

No - nothing

Very strange....
