You Are Right Kano by 90 %
But please answer the last question .
why when block discovered elsewhere all miners's bestshares still working and only pool's minesrs has been rest ? (sorry for my language )
solving Block anywhere not effect my work expect my pool 's group !!
I think I will run my miners alone in solo tunnel until I solve the block without Disturbance
This is my point
If my point is wrong I will sell my rigs and I 'll let insects live with me in my home .
As I already said:
Best share is a random statistic - it has no actual meaning to when you will find a block.
It simply shows how close you were to finding a block.
Block finding is not a gradual process.
You either find it on each hash you do or you don't.
Each previous hash you do has no effect on the next hash you do.
A 1THs miner does 10^12 hashes per second, but the chance of each one finding a block is unaffected by the previous ones.
Each one has the same chance.
If I find a 3 billion diff share, it is worthless on solo - it also has no effect on when I will find a block.
Knowing best share makes no difference at all - and also part of the reason why I've not yet bothered to show it on kano.is since it causes this type of confusion for some who don't understand bitcoin mining.
Maybe another example might help:
Someone makes a lottery of 1000 tickets worth $10 and only one winner who gets $5000
(yeah that's pretty shady - but you'd be surprised how often people part with their $/BTC under such shady circumstances
)
The tickets have a number on them from 000 to 999
If the winning ticket is 808 and you had ticket 809, you were close - but - so what? You get nothing and it wont change your chances if you buy a ticket in the next lottery.
