In your data do you ever have any where a new stream starts for a streamer before the last stream ends?
I have some things like this:
id twitch_stream_id streamers_id beginning end status
519949 23313803328 19660 2016-10-02 15:06:46 2016-10-02 15:34:49 1
520099 23313950976 19660 2016-10-02 15:27:28 2016-10-02 15:55:17 1
It’s a little odd that a new stream would begin before the previous one ended.
