Totally insane hashrate 
why isn't your pool getting any blocks? you turn scammer on us or you just really unlucky these days?
Did you have a look at the Nethash ? There are like 15 GH/s on the pool where the nethash is somewhere around 100 GH/s.. So we have like 10% of the Nethash and get around every tenth block which sums up.
With your Hashrate you get the same on a pool that gets every block or on a pool that gets every tenth block, you simply get bigger chunks from the blocks.
