Questions about daily interactions

[luhongyu]

Hi,
We have two questions about the daily interaction feedback.
First, we found that some of the interactions occurred before we submitted the results, including the user-work pair we also recommended. So, I wonder wether such impressions(or interactions) are generated by other teams or XING, and wether they will be used to calculate our score?
Second, the daily target users have a partial overlap with the users released previous days, then if we recommend a new work for this part of the users, will it coexist with the works recommended before or cover them?

Thanks.
