how does PM calculate effect hash and at pool stats?
Why are both of those numbers so much lower than my hash rate even with zero rejects?
Q007: What is the meaning of "effective speed" shown by PhoenixMiner's statistics?
A: This is a measure of the actually found shares, which determines how the pool sees your
miner hashrate. This number should be close to the average hashrate of your rig (usually a 2-4%
lower than it) depending you your current luck in finding shares. This statistic is meaningless
in the first few hours after the miner is started and will level off to the real value with
time.
Q008: Why is the effective hashrate shown by the pool lower than the one shown by PhoenixMiner?
A: There are two reasons for this: stale shares and luck. The stale shares are rewarded at only
about 50-70% by most pools. The luck factor should level itself off over time but it may take
a few days before it does. If your effective hashrate reported by the pool is consistently lower
than the hashrate of your rig by more than 5-7% than you should look at the number of stale shares
and the average share acceptance time - if it is higher than 100 ms, try to find a pool that is
near to you geographically to lower the network latency. You can also restart your rig, or
try another pool.
