I come with my 24h test results:
I have to be honest... I'm really surprised with the result of the miner, I was complete incredulous but after the 24h test, I see an amazing result, reported is nearly like average. The result after 24hours in at the pool.
Reported = 689.7 Mhs
Average = 686.9 Mhs (with my previous miners I was around 674-680 that's nearly 1%-2% less)
Stales are also really good a bit lower than before, but that could be something with the connection.
