hi ^^
Hey, just want to say hi to the community of BlocksFactory.
I am new with PhenixCoins and gonna mine in your pool (at low 300MH/s)
hoping that pxc going to be worthwile in the future

Come, we are in chance :
The 2 pxc extra reward is still effective
The 2 pxc extra reward is still effective
extra block reward is now 2 PXC come on !
come on miner we need to mine PXC to become RICH
Keep it up
extra block reward increased : 1 pxc
pplns is now fine !
pplns is now fine !
Big problems are on this pool
We missed a lot of block today.
Unfortunately I should out!
We actually missed 5 blocks in the last 24h ( 5 orphans) but it's normal when hashrate jump from 80 Mh/s to 700 Mh/s without diff ajustment We missed a lot of block today.
Unfortunately I should out!

Alright, this is getting very suspicious.
Again, consider the last 2 hours: http://pxc.theblocksfactory.com/blocksAuth
Within this timeframe we have been at an average hashrate of 70MH/s per second which (at 1 block every 3 minutes, as specified in the pool statistic itself) should have produced 2 * (60/3) = 40 blocks.
Yet the pool apparently found only 12 blocks, namely: #42879; #42793; #42758; #42736; #42678; #42673; #42653; #42648; #42626; #42614; #42609; #42600
The probability of finding no more than 12 blocks when 40 blocks are expected is:
where F is the cumulative distribution function of the Poisson distribution.
No idea what exactly is causing this (scam, technical issue, or some kind of attack) but this is far far below all reasonable or common significance levels in statistical tests, meaning the chance of this happening simply by chance is so incredibly small that believing it would be exceptionally stupid.
Also rewards are completely missing for certain blocks.
Well that's it, I'm out for good.
EDIT: And another one which took 31 minutes while I was typing this out: #42966. Yeah right.

more miners come in your pool now so it's stable 
This smells fishy.
Over those suspect 2 hours at the average hashrate of 50MH/s or 1 block every 5 minutes we should have gotten: 2 * (60/5) = 24 blocks.
Yet we only got 8 blocks. (see http://pxc.theblocksfactory.com/blocksAuth)
Block generation is a Poisson process and the probability of finding no more than 8 blocks when 24 blocks are expected is:
where F is the cumulative distribution function of the Poisson distribution.
Not exactly likely.
UPDATE: Seems like the blockrate has been suddenly back up to normal while I was editing this post, not sure what to make of it. I first deleted the post after seeing it's back but now decided to post still because of the statistical peculiarity, let's keep an eye on it.

Close to one hour now, and no new blocks??
No blocks in 30 minutes? Is the pool really having that much bad luck or is there something else going on?
My payouts went from ~11 pxc per block to 4.5 without a drop in my hashrate or a rise in the pools hashrate or accepted shares. I'm guessing this was around the time you changed the N shares, and it may have reset the total shares? Im back on, we'll see how the lower N value goes. May I inquire on what you set the value as?
i set the value at 5000 it was 20000 beforeIn theory, you should see you Payout going from 0 to expected hashrate slowly when you join a pool who pay in pplns

Now my payouts dropped to half of what they were reported as. I may be back if you can fix your pool. This loses a lot of trust though.
You can see on the transaction page that your unpaid share has been paid after, on the blocks mined after you left.
OK, thanks. Things seem to work as advertised now - I guess I was just a little impatient (and confused by the finder's fee being paid before the work) :-)
I saw the problem, the share of the 1 or 2 first blocks is not counted directly when there are mined.
But there are counted after.(PPLNS works like that). payout are calculated on more than one blocks
the problem is that the shares should have been counted before and not after
I think it's cause by the pplns n parameter who is too big.
You are paid for your share it's just take longer
i will change the parameter to have a faster and better adjustment
