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

My point is to give my miners a enough time frame to solve a block without resting bestshares .
and what about Pool 's Luck ??
EX :

Maybe I'm Right or Wrong
