What is Bestshare really?
Why does 4 numbers appear after the dot?
Within the Asic diffA and diffR appear, why does it not match the CKPOOL data?
I'm trying to understand this but I can't find the information I need to fully understand it... Please someone explain it to me in the best possible way.
I use a translator, I am Spanish.
Bestshare is the value of the highest share you found since the last block was found by someone on this pool. Bestever is the value of the highest share you found ever and never resets. Assuming you are using an antminer then the bestever of CKpool should be equal to the bestshare in the summary of the antminer miner status. As to the 4 numbers behind the dot: share values are not integers but floating point numbers* and can be rounded down any way you want. CKpool rounds it down to 4 numbers behind the dot and antminer rounds it to whole numbers.
DiffA is the value of the last share Accepted by the pool and DiffR is the value of the last share rejected by the pool and both continually change up and down. CKpool does not show that information. What you are looking for, again assuming an antminer, is the accepted stat under pools. That should correspond to the shares stat on CKpool.
