None that I'm aware of; the exchanges are not performed by the pool (the exchanges are Bittrex, Yobit and Poloniex).
Please can you provide the information that you are looking at to make the comparison?
I am not even going to bother. This pool is dubious, here-today-gone-tomorrow.
Dubious is not really the right word but it can be quite confusing to a lot of people. Looking forward to the new dashboard.
