Also true... although the tough part is writing a script that can accurately predict a pool's luck. I'll get on that right after I finish writing the script that will tell me the next numbers in the lottery...
its not the luck you are after it is a block being found.
if u r on pool x for 5 hours and pool x doesnt score like slush where leaving nets u 0, and script sees slush just found a block, then move all to slush hoping for a quick block. win win if it happens with that kind of speed.
then u just decide what to do if the next block takes more than 2 hours or something.
what do these people care, they have 500gh/s+ and most likely have 1000's of btc.
many rich people are greedy and need schemes to milk every drop.
OH... also some have other pools set as the backup... so if other pools are being syn flooded then their SCRIPTS would move them to slush if slush was the backup.... regardless of luck
And how, exactly, is that not just a method of attempting to predict luck?
1st off any decent mining app has failover capability not need for a script... if yours doesn't I suggest switching (cgminer is my personal pref).
I am happy being the tortoise rather than the hair but if I was going to attempt to outwit luck it would go something like this:
Personally I would consider mining constantly on a PPS or PPLNS and only switch to slush when the following condition occurs:
Take the last N rounds (probably 100) on slush, round them to the nearest 15 minute mark (so 18 would = 15, 24 would = 30, 65 would = 60, 207.6 would = 215, etc...) and then take the arithmatic mode of that list, subtract 10 minutes and if any given round on slush hits that time mark, I would switch to mining Slush with the hope that Slush would find a block about 10 minutes after I switch over so I get paid full share on slush and all my PPS or PPLNS are making money.
But I would still be trying to determine how lucky the Slush pool is.
