What percent of rejected shares you have? Not percent that showed by miner. Just take all rejected shares and divide by all shares and multiply by 100.
Currently running at 0.54% rejected. What do you think. Too Hight ?
No, it's not too high... But TR even on nicehash gives only 0.3%. You mine not on nicehash?
No, I use ethermine. Started with them way back from day one.
Once I find something that works I usually stay with it. But, if there is sufficient reason to change I will always.
Nicehash just usual have more rejects than other pools. So PM on nicehash gives more than 0,5% rejected shares. For me difference between PM and TR in speed not so big as difference in rejected shares. TR is uses less power then.
