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?
I think you found the 2 blocks before I implemented the best ever statistic so there's no record of it

Yes diff is pool percent of current network diff as OSM said.
