Hi Marin - A year and a half late is better than never, right? I'm sorry I overlooked this, and a bit embarrassed that that little blunder (2-5 times or more) stood for so long. I hope you figured out that it was a typo - users are not counted twice in this setup. It's 2-5 times and 6+ times.
As for changing the segment, I also hope you figured out you can simple remove the segmentation and add your own.
If you need help, feel free to reach out to me via email. My name @gmail.com.
