Not sure what you are talking about. I got paid every 6 hours so far from the beginning on.
you can check your hashrate and shares as well as payouts from their homepage.

Did you find a way to only use pcie gpus? I couldnt manage. I really lowers the overall hashrate though.

Using bit-pool.net miner now. works like a charm. Higher overall hashrate, lower use of other system resources (integrated graphics and processor)
i found that after 2 days payouts are also reliable and true on bit-pool.net

anyway, pool site and stats are way better on eggpool. so i would actually like to mine there. But my shares there were much lower, and the hashrate with their miner is lower as well due to the disability of switching of the intel platform.

found this as well on eggpool github, it might help you:

which miner are you talking about? the one from eggpool, bis-pool, or acc-pool ?
