Hi,
website https://blockchain.info/pools is not focused on HF. These are global statistics.
Our website directly measures data of real accounts of the Hashflare.

How does our website work:
We have registered 5 separate accounts on Hashflare. Each account has only one specific mining pool set up. We compare the BTC revenue per 1 TH/s of each account every day and analyze it on this website.

Thanks for sharing.
