I've been mining hush for a while now (probably 2 months-ish), both at hushpool.cloud and at madmining.club, and I've noticed my payouts are consistently around 25 or 30% less than what I'm seeing on whattomine.com.
I have about 1k Sol/s, and according to whattomine I should be getting 2.2/day and instead I got 1.7. When the difficulty was lower and I was supposed to be getting 3.5 or 4, I was getting 2.5 to 3, etc.
When I was mining on hushpool.cloud I would look at the stats and the pool luck was always at -30% over the previous 4 days (or 7 or whatever the number it was using for the average)
At madmining I don't see the actual luck, just the calculated luck (what it should be getting) but I assume it is also getting bad luck.
What gives? Is this what you would expect to see happening if someone was doing a 51% attack? I understand bad luck can happen for any given day or even a period of days on a fluke, but consistently over this long a time frame? Seems like something is up.
What to mine is a point in time estimate based off a moving average I believe. Hush having a small network hashrate can have large swings in difficulty throughout the day. A large miner or private pool points to hush and say has 1MSol/s (roughly 25-50% network hashrate) for 20 or so blocks then moves to another algo while we are left having to deal with a high difficulty for a few hours.
This can skew earning a lot... This happens to other coins but if you look at zcash 350MSol/s 1MSol/s miner will not make a huge impact on the network like it will to hush with 3.hMsol/s
So, while yes whattomine cannot give a good estimate you should be close when you look at 7+ days
A good gauge is to look at shares per block, with our current hashrate I would expect most to be under 100k shares
https://madmining.club/blocks you can see we had 3 well over that. This is a combination of luck and swings in difficulty (which you can see here
