This is so true!
Especially, there is no sense have 2 same type pools (dbix1 and dbix3) and compete with each other... Isn't better to rise last shares number from 3000 to 10.000 at first pool?
That probably means, the current shares found on N=3000, will be discarded when it change to 10k.
You do realize those shares are discarded 13 seconds after you find them, unless the pool finds a block, right?
A share is not worth anything unless its one of the last 3000 shares (in this case) found when the pool finds a block. When a block is found, the pool will look at who found the last 3000 shares and then distribute the block reward to those accounts. So if the last share you found was a share 4000 shares ago, you will nothing of the block reward, even tho you found a share 20 seconds before the block was hit.
