I don´t provide a friend link for readers, so i have no advice to offer on the pay scale...but i heard a rumor about the boost from another writer on another platform. The writer said there are FB groups that all the boost people are in, and they work to get their own work boosted.. like other editors promote their friends, etc. and i am inclined to believe this. So essentially the boost program is unfair, and only benefits those who are the nominators and their friends.. but i am just gossiping maybe its wrong info, who knows.
