Best share is best share this block, best ever is best ever share found. It's per worker, and overall for the user.
I have found 2 blocks on your pool, I would love to see my best share ever on my page. I do like the way my stats page is now, opposed to all one line. Makes it easier to find everything on mobile.
Is the "diff": 179.0" from the pool stats page mean the entire pool is at 179% of current diff?
