I have been mining for 6 hours with 3 miners, rejected + stales stabilized at about 5%.I think there are some time-frames that this appears to be higher or lower, but the overall reject rate, according to cgremote is that, which I think it is fine...
That makes sense. The timeframes of higher and lower rejects are just timeframes of mining different coins. Some coins just give more rejects than others. We are still mining them though if the profitability difference exceeds rejects difference.
