One of my ants shows a significant difference in hashing between what miner software is showing (191) and what eligius pool is showing (187) over the same timeframe (12hr). Is this a fee or something wackier?
Not sure how a fee lessens your hashrate and eligius has no fee anyway.
You are comparing a true running 12hr avg to a "lifetime" avg (i.e. since the antminer was started).
you are so close I'm pretty sure you are ok.
