After mining for a few hours, the balance that each rig below was contributing to the next 0.1MNX payout was roughly equal.
However, 6 hours later the hashrate on the lolminer rig was still high but is producing significantly less crypto.
The balance listed below between the two rigs should be roughly equal, but it's not even close.

Worker   Hashrate (Now)   Hashrate (AVG)           Diff.           Shares     Balance
nvidia   167.23 KSol/s           167.67 KSol/s           1495173   547.55   0.04332093  (EWBF Cuda Equihash miner)
amd     157.71 KSol/s           147.99 KSol/s           1462857   714.29   0.01504778  (lolminer v0.41)


Why is this happening? V0.34 had a lower hashrate but was producing more crypto in the long term.
This is the exact same behavior I saw with version v0.40

**lolminer v0.41 did fail twice during the time I was mining. Both failures were due to: 'Floating point exception(core dumped)'
**I have a script that restarts the miner in the event that it fails. So these failures resulted in only a minute or two of downtime.

switching back to v0.34...
