Thanks East, great suggestions. Will keep these in mind for future contributions. The overlap is overall data. That includes posts made in either DTube and DLive, but are also have YouTube video/s in the post. About the top authors who showed up in more than one platform, I could have simply said it that way.

acidyo is the only author who showed up in both lists of top authors using DTube and Dlive. Which tells us that the two dApps are catering to different sets of users/interests.

Thanks for reviewing my work and the compliment towards the end.
