Yep. If they have 40% overall invalids. Just Christian's rig if he can get it to 15khash/s would be over 1% of the global hash rate.
As the global rate would be about 1.2Mhash/s
Hell my rig is almost 0.5% of the global hash rate.
The cudaminer pool! One pool to rule them all! :-p
Edit: And oops, I did mean to put 47 not 27, my fault
Actually, the yac.coinmine.pl pool is 1.5 MH all by itself - That pool is reporting over 2 MH as the overall hashrate, which sounds abut right with the way the difficulty is growing.
