You assume an awful lot... I've never used NiceHash, not even once. I switched a couple of my rigs from equihash to lyra2v2. I've tried a couple of different pools in the past 2 days. I like that this pool converts to BTC automatically. However, I would love to know why THIS POOL reports my hashrate at roughly 40% of what my miner reports while a couple other pools report it almost dead-on with what my miner reports. If it's just a reporting problem on the pool side and I'm being paid fairly, then I couldn't care less what gets reported and will keep mining here. But if there is some type of problem and I'm only getting credited for 40% of my hashes then of course I will mine elsewhere.
And since you have more than 50 posts, I'm sure that makes you a bonafide expert on this topic... so please do us all a favor and provide the answer!
Most of these pools really don't know what your miner's true hash rate is. It can only guess the hash rate by looking at the number of submitted shares vs your difficulty. The actual hash rate of your rig doesn't mean squat if its not making valid shares.
100% valid shares according to the Zpool. Suprnova reports hashrate accurately - the reported rate bounces above and below what my miner reports. Zpool consistently shows the hashrate bouncing above and below 40%. All I really care about is whether I'm being compensated fairly.
