Sure.
If the community tips 2 million coins during the tipping event you would get 10% back of the coins you tip. I think it's rounded up. So in your case you'd get 3 coins back.
If the community tips 5 million coins during the tipping event you would get 20% back of the coins you tip. And in your case you would get 5 coins back.
If we reach our goal and the community tips 10 million coins you would get 30% back, meaning 8 coins.
Hope that helps!
