Re: [8500 GH/s] Slush's Pool (mining.bitcoin.cz); TX FEES + UserDiff; ASIC tested
The "non-exp value" column was just a straight %-based calculation (my % of shares as part of the total - 2% fee). For the record - my average hash rate is around 900MH/s.
This might be a good idea to add to calculation. It shouldn't be hard... So users can see benefits that they don't see. You only see where you got less and complain.
So although on a few rounds I was significantly towards the losing end, it seems the rounds where I was closer to the winning end not only compensated but actually I'm at a 1.19% bonus 
This is what I'm saying all along... You get something extra from not fulltime miner(hoppers, undedicated rigs, people with problems during the round end)...
