I confirm, on this pool always an understated hash, on all algorithms.
It doesnt affect on payouts, because we pay for the total hashrate percent. So its mean that if hashrate for all miners in your pool are shown lower than 10%, the total hashrate of the pool is lower on 10%. Hashrate is an abstract value. If 10 Mh/s from 1000 Mh/s is 1%, so 9 Mh/s from 900 Mh/s is 1% too. Its an elementary math.
