The 15-25% will be taken from the 75% of your author rewards, while the remaining 25% is taken by Steem for the curation rewards. So your earnings are 75% of the total amount your post got, minus 15-25% given back to the Utopian Sponsors and Moderators.

Thank you for this clarification, this is what I was trying to get last night in the Discord channel and also by watching the video on the subject, however it still wasn't clear.

Now I understand I can move forward and hopefully post for Utopian again.

Steem on! :-)
