I like that it's being dropped in small bits at a time. It forces the swamp to make up a story without knowing what's coming next.
I did this with my cheating husband. I purposely slowly dripped what I knew and in his effort to cover his ass he buried himself and caused his side ho to lose her alimony and both of their reputations. If I had shown all my Reciepts at once it would have been easy for him to craft a full cover story.
