OK
What about Fact that hashing power will solve a block in period time frame ? 100 TH will generate a block in 20 days and 10 Th will generate block in 90 days

Your hashing power doesn't decide when you will find a block.
It only decides the expected average time to find a block ... average over maybe a few thousand blocks.
My point is to give my miners a enough time frame to solve a block without resting bestshares .
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.
Imagine someone says to you, if you give me $1 and you roll 9 sixes in a row I'll give you a million dollars.
You manage to astound everyone and roll 8 sixes in a row, but fail on the 9th roll.
Close - but - you get nothing

(and by the way, he has a good ~10x "house edge" if everyone gives him $1 to try

)
Yeah pretty cool hey

So If I mine in 5 Pools I will have more chance to got good Luck
Maybe I'm Right or Wrong
You can't affect luck.
You can reduce variance.
