Network vs Miner Difficulty

[BitCoinPokerBro]

Why is my miner's difficulty always so much higher than the network difficulty?

For example

Network


Miners


Does this affect mining efficiency?

[iLiekPai]

The difficulty that the pool gives you has nothing to do with network difficulty, it creates a barrier below which shares are not submitted - you have to make a calculation/share over your personal diff given by the pool so that it'll be submitted. It can become a nuisance if the pool gives you high diffs due to bad estimation of your hashrate, but in the end it balances around yours.

Would it be more efficient to add all of my cards to one miner in hopes of a lower collective difficulty?

The more kh/s, the more diff it will give you. If you want lower diff you can assign different workers to every card.
