I have like 0-5% stale shares in random periods... it is like 3-4 hours with 0-5% stale shares then 1-2 hours 0% stale shares then again 3-4 hours 0-5% stale shares... and so on and so on... Also, my average effective hashrate and reported hash rate are so separate? like more than 5mh/s... My rig miner is reporting 90mh/s average and in the pool i get like 83 Average effective hashrate... its like i loose 7mh somewhere ?! Please give me advice how to fix that.
