RO Active points challenge - "Exactly how many points" popup

It would be good if when I click or hover on the avatar of the challenge competitor in front of me or behind me to get popup with exactly how many points I need to make for "my average" to catch up with challenge competitors average or how many points the user behind me needs to catch up with me.

We are currently showing the avg in the current challenge and I have to calculate it in my head every time and a small popup would solve that.

That calculation would be something like

(your average - my average) * number of passed days in the challenge
