Duelbits paid him 10% of house edge. If the income from house edge commision was the same from $25K and $180K wagering from different websites, that means that another website paid him (let's assume that website also has 1% house edge) 1.4% of the house edge.
By the way, sometimes I have even see casinos offering 50% of house edge, that is definitely the greatest reward one can gain through affiliates on casino.

I don't know much about Duelbits, but never believe the titles that companies claim. Definitely, everyone will tell you that they are the best but you shouldn't actually believe that they 100% back it up.
It's good that you created SA thread, I hope your problem will be solved because Duelbits doesn't want to ruin reputation and if there is some misleading, I believe that will be solved! Just saying, if I were you, I would try to make that thread a little short and more focused on actual problem because people don't read long posts.
