This tutorial is really useful!! Very well explained :)

I only want to add that there are also rewards for the beneficiaries (this is done when you use esteem, utopian, dtube, etc), and also mention that the curators must upvote after 30 minutes in order be well rewarded :)

For more details about the maths I posted some info:

• infographic of reward system
