I'm open to some feedback on a fun little perk on doubling someone's hash, but unless it's for a 5nd period, it will never get the full benefits.
...
If you mine for 10 hours at 4 TH/s you expect to get rewarded 10 hours at 4 TH/s
The 5Nd is only how the reward comes to you to reduce variance ...
which is from when you start until 5Nd after you stop i.e. start + 10hrs + 5Nd

I must have confused myself somewhere down the line just when I thought I understood it correctly. Can we expand on that example a little more? My brain catches on quicker with a detailed example.....

So, let's say someone has been mining for at least enough to have ramped up their 4 TH/s and was awarded another 4 TH/s as part of a giveaway and a block was found around 200 % difficulty from when the reward was added. To be clear, it only counts back shares equal to that 2Nd period since the last block, correct? Then the promotion expires and the extra hash starts to ramp down and another block isn't found until say another 300%. Those 2 blocks that total the 500% end up paying for the entire 4 TH/s that was added spread out over subsequent blocks up to 5Nd, no?

This is how I understand it and I'm confused why I worded it the way I did above. It was Friday and I had the weekend on my mind I guess.

I do have the correct understanding of how the 5Nd pays the shares though, right?
It's easier to think of it as I said Smiley

If you mine T TH/s for H hrs then you expect to be rewarded exactly that T for H hours.
and that expected amount is 100% PPS times the MeanTxn% minus the pool fee (0.9%)

The PPLNS process means that you wont get that in the next reward, you'll expect to get that over the H hrs + 5Nd after you start mining
which is of course 5Nd after you stop mining (since you mined for H hrs)

However that bolded word expect is important.
It means that's assuming 100% luck and 5 blocks in the next 500% (5Nd) each 100% apart.
What actually happens will depend on luck and will of course never exactly match that.
Long term you expect to average out 100% luck, but short term mining is VERY much luck based.

So if there's only 2 blocks in the 500% (5Nd) then your reward will only be about 2/5 of what's expected.
If there's 8 blocks in the 500% (5Nd) then your reward will be 8/5 of what's expected.
Again, what's expected is the 100% PPS value of T TH/s for H hrs of mining (times the MeanTxn% minus the pool fee)

If you have other hash rate already going to your account, that can be ignored for this calculation.
This calculation is to work out what will be added on top of whatever is already going on in your account.
It wont change the calculation of your other hash rate reward - it's simply added on top.

Edit: I guess the clearest way to understand this is from the following lines in the Help->Payouts page:

The 5Nd means it takes that long to reward your shares.
The ramp isn't missing rewards, it's delaying them to reduce variance.
Each share is rewarded in all the blocks found in the 5Nd after the share.
That's simply how it reduces variance. Each share's reward is averaged out over the 5Nd after it.
The important part to understand is that the reward process works on each share individually.
The shift a share ends up in, determines how many times it will be rewarded.
The number of times a shift is rewarded depends on how often the shift is inside the 5Nd of a block -
but the value of each reward the share gets is based on the difficulty of the share itself.


so i have been mining for less than a year. i have to say i have learned a lot. i know how this pool works and i am perfectly fine with it. i also love the community aspect in it. i also understand why some people dont mine here. now i will be honest, i will need to seat down and read this one a bunch of times to see if anything sticks because its a big mouth full to me, i usually understand better with graphics and visual stuff, my little brain has a hard time remembering too many sentences in a row. i will keep reading and MINE ON!!!
