Great read and thanks for posting that Con.

Here's my thread regarding suggested difficulty settings. Read it carefully for there is no right or wrong value and you will not be losing money or efficiency regardless of what the setting is.

No issues running my saturn at 256 shouldn't the jupiters be higher to be more efficient?

We can change this manually still, right?  

I'll be putting a couple Jupiters on the pool in the next few days, and I really don't need to be sending 20 shares per minute with 8 different workers.  Since I understand how pools estimate hashrate and that it doesn't matter - given a choice, I'd prefer to have my Jupiters submitting at about a 2048 share difficulty rate...

It is becoming obvious that the lower share rate per minute (currently at 12) is causing miners anxiety so I will probably change the setting to something around 20 shares per minute.

I have explained that the lower share rate causes bigger swings in 30 minute hash rate, but this is not a viable solution to keep bringing in enough new hash rate to keep up with the network.

Can you change this for me aswell? I have a Jupiter and it mines at difficulty 640 atm.
Can you change it to 256 please? Also there is some issue with the reported hash rate, cgminer shows 550-580 GH/s, Pool shows 420 GH/s. someone else mentioned this also (scroll up).

Nickname is jeroenn13.

Thanks!

I changed your settings to be inline with the best settings for the miners. You are welcome to change them back.

you may want to look into these calcs   seems a little too good to be true

Looks like its back to normal now. Something on my end overnight perhaps. Will keep a eye out.

Yummm green.

So how do we sign up to get a "ka-ching" on our phones when the pool finds a block?  And yes, Green is good.  Even black is OK.  Just not red, please...

Reported hash rates are normal from my perspective. All the pretty green looks good on the stats page too.

Seeing about what I would expect here - very close to what my mining software shows.

Does anyone else see weirdness with the reported hash speeds?

There is no "equation".  Ckolivas from cgminer recommends hashrate/1.6 rounded to nearest power of two.  Other people recommend hashrate/1.4 but there is no set "correct" value.  I've seen 400 Gh/s people mining at diff-2, and I've seen 336 Mh/s USB miners mining at diff-25.

All that difficulty does is specify how many shares per minute you send to the pool.  At diff-1, you send them all.  About 1/2 of the shares end up being diff-2, and about 1/2 of those end up being diff-4, etc.  

A pool can only estimate your hashrate based on the share diff selected and the number of shares sent per minute over some period of time.  That estimate can easily be off by +/- 25%.  

There is probably nothing wrong with your setup at all if a pool is estimating your hashrate at 450Gh/s and your miner is showing 500Gh/s.  It's your miner that counts (literally), not the pool estimate.  You are paid by share submitted * share diff, not by estimated hashrate.  The only way this could be affecting your payout is if you were mining in a pool that tended to hit a great many blocks in just 30 seconds or 1 minute each - before you had a chance to submit any shares at the higher share diff level.  "Bro, they ain't one like this out thar.."

A stratum pool adjusts your share difficulty based on how many shares you are submitting per minute.  Sometimes you might submit 100 diff-256 for a period of time, and sometimes maybe 10 - the pool tries to keep the number of shares per minute constant.  This adjustment should not affect the payout.  at 512 diff you should be submitted about 1/2 as many shares as you would at 256 diff, but getting paid twice as much per share.

Pools can certainly dynamically increase the difficulty as they please, my Jupiter's difficulty is 640 at the moment, but why arbitrarily change the settings for all my workers ?

Its 120blocks after its find, you can see how many confirmations a block have on the stats page.

You'll just experience more variance with a higher difficulty, there can't be any other effect. Unless the miner software is buggy and doesn't handle dynamically changing difficulty well. To rule that out, it's best to select a sufficiently high minimum difficulty, so that it won't ever be increased dynamically. That's where the hashrate / 1.4 rule comes from. But it's not valid for this pool, because it assumes pools want miners to submit 20 shares per minute. This pool aims to just 12 shares per minute, so try hashrate / 0.84 (625 for a 550GH/s device is quite close to this).

My workers are all named
jupiter1
jupiter2
jupiter3
saturn1
etc

I just noticed all of my jupiters have had their difficulty set to 625 and my saturn to 250

I think this has had a negative impact on my hashing speed as the equation is supposed to be hashrate / 1.4

I used to have the jupiters @ 256-400 min difficulty and hashing of 550+ for the best jupiters.  Now all units =<499

After 120 blocks

In 3 months that will be what you need to find a block.
