I had to switch to another pool because I was earning more with their share difficulty. Now that yours is the same (31), I'm back here. It's weird how much your earnings are affected when share difficulty isn't set to something that's optimal for your hardware.
I have good news. I'm putting the finishing bits on a VARDIFF implementation for the BBQ Pool!
A Custom VARDIFF implementation matches your miners with the perfect ShareDifficulty for their hash rate.
It should be online in a week or two.
SWEET BBQ !!! Thanks.
