Thank you.
The calculated hash rate in nanopool is varying from 102 to 0 but the reported hash rate is static at 39. Realistically the 102 is impossible so I am presuming the calculated hash rate is simply unreliable?
No and neither is 0.
think of dice. tossing 3 or 4 straight sevens is hard to do that is like a 102 hash rate it will pop up once in a while
tossing snake eyes back to back is very hard that is like the 0 it will pop up once in a while
39 avg is the one to look at
if you do long term 37-41 you are good.
If you drop to 30 or 31 long term something is wrong.
For arguments sake say 3 days = longterm.
