That's a community built, third party stats site @ash. https://runestake.info/

Also if you check the twitter link from poshbot, there is a much more powerful analytics set up (also community built) called Thorchain skittles. I haven't jumped in to use it yet as I think it may be a bit advanced for my skill set, but I'm having a look at it over the weekend and will let you know if its good. @khaleelkazi wants a guide, so if I can understand it I'll probably make one next week.

The Runestakeinfo site linked is dead easy to use.
