I find the efficiency<1 comments odd, unless you only mined at multipool for a small number of unlucky hours. All the accounts I've looked at (which mine long-term) have efficiencies around 1.15-1.25

Wrote in the past in original multipool thread, but it would be more fair to deduct fee in long term - for example 10 or 15% of over 1 eff once before payout rather than 5% of every over 1 eff round.
