Could someone explain the round shares and how it works?
From what I gather it is your round share at the time of discovery is your cut?
Yes..
roundshares, or as I prefer to call it: N on pplNs (pay-per-last-N-shares), decides how much you get on a block.
for N = 3000, you have to find at least 1 share from the last 3000 shares, to get your rewards, in this case 1 share means 1/3000=0.0333333%. and more if you get more shares, accordingly.
for N = 100000, similar thing happen.
Only in N=3k you are like gambling, hoping you will statistically get one of the last 3000 shares before a block found. in N=100k, you are almost guaranteed to get your reward proportionally. At least at current difficulty.
The thing is, 1 block difficulty is only about N=60000, right now. So there is quite a big possibility, that you get rewarded by the same shares you have been rewarded before on the previous block.
You can check this with your miner, that share difficulty is 2000MH or 2G, despite the pool page says its 4G. And with block difficulty almost 120000G, a block will be found every N=60000.
We just need to make it faster, to get faster rewards.
if you have 100 MH/s on current 50GH, your proportional rewards should be 0.2%.
But on N = 100000, your reward on the first block will be your shares/60000, and the next is, (some of your previously rewarded shares + shares on current 60000)/100000, and so on.
So it would probably look like this, statistically:
#1 block, you get 0.2% x 6 coins
#2 block, you get (40000/60000x 0.2% + 0.2%) x 6 coins
#3 block, you get (40000/60000x 0.2% + 0.2%) x 6 coins
..and so on.
So, slightly more than you should get based on shares you solve on a block.
There is a window before block difficulty equals to N=100k, until you get similar to prop, but without the pool-hopper negative effect.
