If the economic incentive to mine in this pool is that bad,
Because it's not, that's just a lie. Our miners have observed 10-15% more earnings than on the competing pools.That statement is clearly false.
Simple fact, there's not 10-15% more BTC per block, than most pools pay.
So unless someone mining on your pool is giving away a very large amount of BTC constantly, to everyone else mining, it's not possible to pay 10-15% more than other pools.
Simple math and logic, alas I know such concepts usually elude you
