It's not my duty to figure out how they split the income. I pay as a fair and satisfied customer:
not trained and no extras - 20 (you just wasted my time)
trained mediocre massage and no extras - 40 (just like any legit place)
trained excellent massage and no extras - 60 (you deserve a tip for being a good masseur)
trained massage and minimal extra (HE) - 60-80 (depending on massage experience)
rest is up to you, but should be commensurate with what you receive.
