I for one would not care what the luck was within a certain time period because it has absolutely no indication of future luck.  As a miner, my needs are simple:

How many bitcoins have I made.
Email me when my miner is down

BTC Guild does that and more.  Plus it's up all the time....

My tolerance for Cyper's whine has hit a limit and I've ignored.  Thanks for the great pool El!
