my auto-payout went through quickly once I hit 50k.
today there seems to be lots of invalid shares,
also what's with the crazy high worker difficulty?
I'm running a 3x 280x rig and usually set it to about 256ish, I'm currently on a difficulty of 1.85k!
The pool uses VARDIFF. Depending on how well your miner is performing, it'll adjust your difficulty.
This reduces a ton of load on the server. It should also increase your miners efficiency over time.
