Does the "response rate" only reflect initial emails? If there is a conversation, then it's going to end eventually, so the fact that you don't respond to an email that says "okay" wouldn't really mean much.
We don't have a response rate graph yet. We do have a time before first response rate graph. Fred is comparing the total number of emails that he gets vs he sends from/to certain people, which is not the same as response rate.
