High end and low end

Q:Why make the low end 8.7?

A:It was kinda hard to determine if I should make it 7.5 or something else. I didn't want to make it 7.5 because it would make a big range, making it unstable. So what I did was add the lowest it was sold for, and the highest offer(9.8) so far. And I got 8.7

Q: Why make the high end 9.9?

A: Well the most recent it was sold for, and the highest it was sold for was 9.9.
