For now at least...
Sure when the pool does a block in 29% cdf it is good for miners.
and when the pool has the roll over feature this one does there is a 1 btc zone of opportunity for the top hasher.
Ie the guy that grabbed 3.9 btc on the prior block is in line for 3.34 if he hits it now.
So he is up over 1.9btc profit from last block
playing 1 btc of it back gives him a good shot at grabbing the 3.34 now.
Of course when you grab long deep 80% pdf blocks its a no go.
I am only running 1 of my 6 accounts
3 1b7093a2 0.11548665 1,374,581,985 28,641,221 mh or 29 th
and it is shrinking as it is up against the guy with 29ph. about 1000x my hash.
EVEN though it shrinks I do have the other ones and they add to .4
so if an early block comes at say 10% cdf or less I can grab .4+ .115 = .515
maybe less if we go to 10% cdf before we hit.
So if the big boy does it I get some pretty large crumbs.
