So we have to run multiple daemons to get better rewards (HPS2)? It seems the pool reward algorithm is wrong? All the shares are equal no matter the difficulty of the share is?

One 10-CPU machine with 1 miner gives 29k HPS2.
One 10-CPU machine with 10 miners gives 120k HPS2.

29k to 120k. it is 4 times reward.
This will let us create many many workers in the pool.
