What are you doing? I never saw a such bad return on my mining, as this thread is looking. I know you don't respond to my PM, so i have to ask here. What exactly are you doing, to get a such bad return? If you follow how Leeloo is mining, then you should not get such bad!
I mine near in same stile as Leeloo is doing, but just a bit different. I did use the same mining stile as she is using, before i talked with Leeloo about mining. But i never get such bad results as you. I also see, that you most mine only at same places and it looks like your good places no longer seems to be good. Maybe try to find some new places. I change my places all the time, especial, if my good places only give bad. I pretty think, if you overmine your places, it never change to be good again.
Dont get it wrong, also if you may don't like me, I only try to help you, like Leeloo also is doing.
