pretty new to mining -- started using the eu eligius pool yesterday, and for the first 12 hours the rate climbed as expected. but starting this morning the expected earning curve slowly flattens out and is now almost horizontal == no new earnings are being added at all. hashing rate has been a almost constant 240mh/s for the past 24 hours.
can anyone explain this behavior to me?
Take the total hashing power of the EU pool and figure out what fraction of that you are contributing. That will be the maximum return you can get per block after it is split up from the 50btc. You were climbing up to that percent but cannot go above that without adding more hashing power therefore increasing the percent you are contributing.
