I have played around with the _diffXXXXX game and agree.  Currently the _diff8192 seemsto produce the best ratio of accepted to rejected shares.  Plus the S/s ratio is also best.

Took me a while but these numbers reflect a 2^n for selection purposes.    In this case 2^13 = 8192.  So you can experiment with different "n" to get your numbers.

BTW. I am running Antminer L3+.

As for the site.  I am not pleased with the "pool" tab.  For some reason my 1GH/d hash shows only 61 DGB/day   I know this is false since I am generating around 300/day. 

Still, Whattomine (an estimator) says it should be closer to 400/Day.  I am more than open to anyone who can explain this large disparity.

Nooblife.
