All mining shares should result in a payout. Shares that go up in smoke is electricity with zero return. It doesn't pay the bills. If the steady miners pay for gas for 80% of a truck haul, and port 7777 for 20%, even if 7777 isn't driving when they reach their destination they should still get paid for their 20%. Mining is gambling, if people pool their money to buy a lottery ticket they all get paid even though only the winning ticket gets the money.
