Hi

Kano, Apologies if this turns out to be the most stupid post of the month so far.

I am just getting my head around how the pool pays by PPLNS, which while I have mined here I have seen the 5Nd period drop from 192hrs to 34hrs as the pool grows.

Never really considered this before today, because I haven't had to sat through a tough block that exceeded the 5Nd period, but I think this block hrs will be greater than the expected 5Nd payment period, which if I understand it, means were only going to get 1/5th of the payment for the last 36+ hrs, and we will loose out on any % payments that we didn't already receive from the previous found blocks, so that for some of the previous blocks we will loose 80%, 60% or 40% of the expected payments should we have continued at the expected 100% rather than this maddening 480% + block that were struggling with.

The only good thing that I can see is that the previous found blocks which we will loose the payments were all quite close together so the loss on previous payments is not so bad, but if we have another bad block as the next one, then we would be loosing 80% of a lot of hours work from this current block.

Is there a point when a pool hash rate gets larger, 20PH+ or whatever, when it hits a point when the 5Nd from the PPLNS actually works against the miners, because the smaller and smaller hrs of the 5Nd period and any bad luck wipes out any benefit of trying to even out the payments by using the 5Nd, is there a point when a pool gets to a larger size to actually run PPS, so to pay for the work done as its done, and then no-one ever looses out on the bad blocks that can over-run the 5Nd period and cause the loss of previous work done.

is PPLNS always best for any sized pool, or is PPS better for a certain sized pools.

If this is a stupid question just delete it

If you do PPLNS anytime you rip back to back cdfs of 99% for your blocks you are fucked.. But just for the two blocks.

The key is think in 100 block segments not 2 block segments. What is the record for the last 100 blocks?

116.05% now if you did PPS at a 99% payrate for those 100 blocks you would have lost out on the 17% over the 99%.

To follow up f2pool pays 96% not 99% and f2pool takes the tx id fees. while give some NMC nets to 96% so over the last 100 blocks so if 100% was 1 btc

you would get .96 btc from f2pool maybe .97 btc

kano you would get 1.16 btc maybe 1.164 btc since he gives the tx id fees.

so .97 to 1.16 is a good estimate for a 100 block period.

But for this block right now PPS is better. Small samples of 1, 2, 3, 4 blocks do not mean much.

a cdf of .993 second best ever
