starting mining Raven, pool question

hi, so as the title said. i started mining ravecoin using NBMiner and i am getting ~48mh/s in the terminal window of the miner, but in the pool i am using (tried both herominers and 2miners) they don't reach that in the dashboard when i lookup my wallet details, i don't know what i am missing here, i hope someone can explain it to me or correct me if i am doing something wong
