So I have a very basic question I would like to verify.  Say I am Mining EtherGem solo through Geth.  That coin Difficulty goes up and down and right now it goes from 700 MH to about 1.2 GH Difficulty.  When I login to my miners and see a miner that has been for like 5 days and it stats the highest difficulty level for found block and it states something like 120 GH, why does it have a result that is some 120 x more difficult then what is needed to win the block?

And is that what that does mean, I found something in the 5 day period at 120 GH?!  If so that is pretty awesome, if that si what it means.  Thank you.
