Could it be related to the current difficulty being under 1? cgminer shows me difficulty 13.3k, but other pools and sites like coinchoose show the difficulty at 0.21.
"The graph above illustrates N shares to find a block vs. N Shares expected to find a block based on difficulty and assuming a zero variance scenario."
Seems like a calculation is off?
This pool's website is fast...damn fast.
I have been testing a new stratum server and tried the difficulty at .21 vs 16 the shares your worker turns arn are crazy, I tried vardiff and it sets the diff at 0 as I don't think it gets the decimal value. What pool has your client showing 0.21?
