When pool hashrate is much higher than network, it may be due to a high number of orphans, so be careful when you do your own math.
That could be the case here, only 25% of shares my hawaii's send to pool are valid.
I modified the pascal cuda miner and optimized it, now it's doing 900 Mh/s on a 1070 consuming just 100W.
Is it good? Worth working on it, now that there are pools?
If zec looses 80% of its current value there are many miners looking for a new coin to mine. Pasc would help nvidia owners a lot, amd cards are currently on 400-600MH range so 900MH would be huge advantage. Definitely worth working.
