I'm going to be pedantic here for a moment...
We should really stop referring to the profits authors receive from Lulu as "royalties." They are nothing of the kind. The authors are the publishers of their books. Publishers do not pay themselves royalties. They make profits.
If a Lulu author were to publish a book for another author and pay them a share of the profits, that would be a royalty. Or if a non-author were to publish books through Lulu, what they pay their authors would royalties. But as the publisher their own share of the proceeds would be a profit, not a royalty they pay to themselves.
