Wrong Results - Collections (Recently Added)

How/Why is it that I'm getting 167 files added last week (which I know is wrong!), but only a total of 121 files added for the entire month?

I would need your database here in order to tell you if and why IMatch might be wrong.
Check the File History of some of the files you consider "wrong". Do they show something that's wrong?
