Email reports confusing ... Damn it!

Hey
Apparently I'm a fool, but using the daily reports of email to write my
Revenue. I think this is why we get them right?

A few days ago I got 2 different reports for the same day, with totally different numbers ...
Now what can I do? I don't see anywhere which is the correct answer.

Can I trust these reports? Or you will get my own reports by using the API as soon as possible?
Can someone help me?
