Maybe the ATX power is helping error rates. I'm getting 6 / 406 now, or about 1.5%. Much lower than last night on the wall wart, about 5%. Neither makes me happy but this is starting to get into a decent ball park.
Now tell me again how to calculate this properly using non 1-diff shares? I can't see a total count that includes difficulty accounted for. I know the git version now counts 1-diff shares, but is there a place to find that count on 3.3.1?
yes you can With little hack of course
...
The code already has those numbers ...
If the code passes a nonce to submit_nonce() it is counted in the device diff1
All nonces found by code go through submit_nonce() (including avalon)
The device diff1 is "Diff1 Work" which all devices already have.
If you want the number of HW errors like you are counting, it is simply the device HW - NMW
Avalon device HW is bad nonces + NMW
No need to change anything.
