Hy guys,
may be a stupid noob question about minin ethereum, but i was wondering why, according to Etherscan.io the average difficulty to solve a block at time of writing is  2,445.94 TH.
But if I take a look to mine rig, that's connected to Ethermine ppol, the difficulty is capped at 4.000MH and gets stuck at that level.

MAy be someone could explain me what's the reason.
Thanks
