On the other hand we were much more lucky before and after. In the end blocks are being found @ average pace among all pools.
SpeedHash is a SCAM?
According to this [1] from block 590 to 711 your pool has not found any block (almost 5 hours!). However if we look at the address you are using for the reward (from block 791 for instance [3] -> CWZKAp7BdeveELrXkpyMUozpujEPAeoWsQ). The block explorer says that your pool has found blocks 637, 645, 663, 680 [2] which means 64 CATc you kept for yourself!!
Even its not our pool, but for your mentioned blocks its just a transaction OUT from the adress. So not the pool has found the block, its just used for a transaction.
