anyway if i understand bc correctly the average sharevalue should be 50 / (877 226 + (2 / 3)) = 5.69978113 × 10^-5 as u said.
That's if each share is difficulty 1. Pool shares are actually slightly lower difficulty, so you get the number I posted.
but why then are urs and the one from bitcoins.lc so much higher? both are overall (2weeks) values, since i began mining. so they should be quite evened out, or does that need even more time? but they are way to high and prop from deepbit is to low @ 3,8*10^-5.
however those values came to be, since one mines for profit, one should join the server with the highest sharevalue.
The past 2 weeks includes different difficulties. At the last difficulty, shares were of course worth more.
futhermore ur case refers to (nearly) everybody hopping, which destroys the gain in both prop and pplns.
If there is ever a benefit to hopping, it is inevitable that everyone will do it, thus killing the pool.
