What can I find out thanks to the Hashtag performance feature?

What does the blue star in the Hashtag performance inform you about?

What does “The top position reached for a given hashtag” mean (in Hashtag Performance Section)?

What does the “Current position in recent posts” mean (Hashtag performance tool)?

“Current position in TOP 9” – what does it mean (in Hashtag performance)?
