Stratum is mandatory when blocks are still coming in this fast. I'm getting 70%+ rejects with the same settings I used on nibble.scryptmining.com (which had <5% rejects with stratum before it went down).
not sure what the difference is but i'm getting ten times more per share on this pool over
http://nibble.scryptmining.comYou're getting more per payout because the hashrate of the pool is much lower, meaning that when it finds a block you get a bigger portion of it. It also means that there are far fewer blocks being found by the pool for now (especially with such a ridiculous reject rate).
