Do you know why you get G level stuff when you are G level? It takes skills for you to get to G level and I am assuming that you have G level mining skills as well. On low rank, your hunter may not be good at mining stuff. So your hunter gets low level stuff and occasionally you get rare stuff because of luck.

So they didn't actually move the stuff around in a map.

For your first question, how are they able to have exclusively high rank monsters at one time, and exclusively G rank at another.

Guild won't let you die, they know from experience which monster is "skilled" and how skilled you are. So, they only allow you to do the quest when you are skilled.
