<span class=hdr>What payout method does the pool use?</span><br><br>
We use <b>PPL${n1}S</b> (<b>P</b>ay <b>P</b>er <b>L</b>ast $n1 <b>S</b>hares)<br><br>
<b>PPL${n1}S</b> means that when a block is found, the block reward is shared among the last $n1 shares that miners sent to the pool, up to when the block was found.<br>
The $n1 value the pool uses is $t times the network difficulty when the block is found - '$n'.<br><br>

<span class=hdr>How much of each block does the pool reward?</span><br><br>
Transaction fees are included in the miner reward.<br>
Pool fee is 0.9% of the total.<br><br>

<span class=hdr>How do the payments work?</span><br><br>
The $n means the pool rewards $t times the expected number of shares, each time a block is found.<br>
So each share will be paid appoximately $ot of it's expected value, in each block it gets a reward,<br>
but each share is also expected, on average, to be rewarded $t times in blocks found after the share is submitted to the pool.<br>
i.e. if pool luck was always 100% then each share is expected to be rewarded $t times.<br><br>
If pool luck is better than 100%, then the average share reward wil be better than $t times.<br>
If pool luck is lower than 100%, then the average share reward will be less than $t times.<br><br>

<span class=hdr>What's a shift?</span></br><br>
When your miner sends shares to the pool, the shares are not stored individually, but rather summarised into shifts.<br>
Shifts are ~50min or less in length, however, when we find any pool blocks the current shift ends early,<br>
at the point the block was found.<br>
A ckpool restart will also end the current shift and start a new one.<br><br>

<span class=hdr>So, what's the $n value?</span><br><br>
The current Bitcoin network value for $n1d is $nv and thus $n is <b>$nv5</b><br>
Bitcoin adjusts the $n1d value every 2016 blocks, which is about every 2 weeks.<br><br>
When a block is found, the reward process counts back shifts until the total share difficulty included is $n.<br>
Since shares are summarised into shifts, it will include the full shift at the end of the range counting backwards,<br>
so it usually will be a bit more than $n.<br><br>

<span class=hdr>When are payments sent out?</span><br><br>
The block 'Status' must first reach '$bc' on the Blocks page, and then is flagged as '$bm', before the reward is distributed.<br>
The block reward is sent out manually soon after that.<br><br>
