Account Level Difference Between utopian.io and busy.org

This might be a feature and not a bug? Please, clarify this for me.

Are account levels computed differently of utopian.io and busy.org?

An example can be my account.

Profile at busy.org shows my account's level as Dolphin:

Profile at utopian.io shows my account's level as Plankton:

I realize that these levels are unofficial and not really relevant nor necessary for the working of both platforms. I would just like to know why there is a difference?

Thank you very much!
