I was thinking the same to be honest. I'm a network manager for an ISP and to me it's looking like there is an issue with the pool servers or connectivity that is failing or reaching capacity at about the 40ph/s level. I sincerely hope this is the case. We've had a few good days at just below the 40 level. So hopefully slush is aware, I'd just love to see more frequent updates in here from him or his team...

If there is some issue at 40ph/s the pool could have a serious problem with variance in the future. I also used to mine at MMpool.org until they couldn't solve one block per difficulty change. But unless the hashrate at kano explodes, the pool will have this problem much earlier than Slush. We also do not know if Kano wouldn't have a similar server/connectivity issue unless it hits such hashrate levels.

As to PPLNS... I know Slush has a similar system and I still don't know why he never implemented double geometric method like mmpool. He wanted to do this years ago to fight pool hopping. Of course as a miner one would prefer PPS but meh.

This is going to sound noobish, but on the vdiff settings, I can either tick the box so it uses the pre set minimum in my user profile which is 8
or untick it and it will set it manually for independent miners which is also 8
so is this just the starting point and the pool still auto adjust per miner, or is it set at 8 untill I change it?

Love how this pool hits 40ph and stops hitting blocks. Can we say withholding!

Now under 40ph and hit a ton of blocks. I have a remote miner pointed here because it's a pita to get changed. All my other miners are on Kano and couldn't be happier

Can you explain how you did that? I wouldn't have thought simple maths is enough to prove your point in this case, so I'm keen to find out how you determined the correlation.

Not trying to belittle you at all and I apologise if I came across that way. I've been working on this problem of Slush's luck for a while -- it's not an easy one to analyse -- and I wanted to know if I'd stupidly missed something simple.

Your maths is fine as far as it goes (EDIT: I was hoping for something that showed how the pool's hashrate affected the pool's luck), but you might also want to consider ways to make the comparisons between pools more valid. For example (assuming your hashrate is constant) compare just payouts over a similar number of blocks rather than similar time period, and I would use a large number of blocks.

Even over a hundred blocks, you're still going to see variance of about +/- 20% of expected. If one pool has a not unusually unlucky hundred blocks and another has a not unusually lucky hundred blocks, there could be a 40% difference between them - just due to variance.


EDIT: Also, if you're just considering time periods rather than blocks, then difference in variance could be exponentially greater.

just noticed it had 2 stale blocked verry close to each other

Yea they fixed it now and adding something extra I seen on his Facebook

Good job sir . lets go slush pool
