paraipan, just an idea to use math to put things in perspective: we can take the two rounds in question 19079 and 19080, and group them separately with the 10 rounds before and after each. then we will use a formula to see the variance between the two groups.

take rounds 19069 - 19079 and add them together. we'll call this 'x' then take rounds 19080 - 19090 and add them together. we'll call this 'y'

then plug the numbers into this formula

((x-y)/(x+y))*100=

if done correctly, that number is your % of variance between rounds 19069-79 and rounds 19080-90.

it should be between 5 and -5

if it's inside of that range then the scoring system is working properly

if it's outside that range then o crap, something's gone wrong. (probably a mistyped number, double check your work!)

I just did this myself, and my variance was 3%, meaning i scored 3% more in rounds 19069-79 vs rounds 19080-90

and i'm a slowwww miner, which means i could actually have greater variance (from 20 to -20) but my variance was only 3, so that's pretty darn good.

Nice, thanks dude but still doesn't explain too much. The shouldn't be so much variance between two similar rounds, that's why we mine in a pool remember?

That's because his definition of variance is incorrect.

Here is what I am thinking.( for what its worth) . if you watch our pool hash rate its jumping up and down quite a bit, so even if your numbers are constant you have others with some large miners maybe jumping on at the tail end of a block which then throws all others that have been mining from the start of the block off. I  jumped off the pool a couple of times yesterday just so I could see how this works and to see what to expect from another pool as I have done all my mining here on slush only. Yesterday on 19093 my shares was only 2078 as I was only on that block for about the last hour but received just a small amount below of what is normal for me (.0064 vs .0072) which in a small way throws off everyone else that was there for the whole 5 hours. Now what if I was a 500GH/s mini rig doing the same thing...instead of my 5GH/s

Well we apparently identified the problem... Thank you for correcting the issue Synethstesia. Our juju is returning in your absence.

My round 19100 is goofy; it will of course be fixed, just saying.

We are on a hot streak!

on my side, 19093 19100 are constant with other reward, but 19080 was 25% less than normal average block reward..

I dont calculate my ratio of variance, because I trust the operator, and I'm pretty satified of this pool.. We have an excellent service too !

Luck has been low this week.. should have a nice week soon Smiley

3.67gh/s close enough!  .005's are only while we are at 17-18th/s that will go to .0045's when we go back to 20-21th/s

Actually if I remember correctly I think 2 miners hash's were not being recorded during this round so I changed their ip's. however keep in mind that was not my fault it was one of slush's servers not synched with the others, as my hashrate is on par. this has happened a few times. slush didnt fix it and what is done is done...

well, you can claim to know about the scoring system, and then complain about it, but that is the reason you got less of a reward for one round vs another. you got paid for the % of your score vs the rest of the pool. you keep pointing back to your shares, but shares are not the full story. they don't reveal if you were scoring higher than average or scoring lower than average, and they also don't reveal how the rest of the pool was scoring.

My score was similar in both rounds.

Was it? Then your reward should be similar too.
Can you post your score, total score, and block reward, for both rounds? You can calculate your reward from those numbers. And see without doubts whether there's an error or not.

Just curious if anyone is using the BitForce 50 GH/s miner from Butterfly Labs. If so, what's your hash rate? I just decided to buy one for fun. http://products.butterflylabs.com/homepage/50-gh-s-bitcoin-miner.html

the early demo videos of their 5gh/s miner was actually running at 5.8-6 gh/s, and can be firmware overclocked to 7gh/s for 100$... so i imagine that their 50gh/s will run well above 50gh/s. (the hash ratings are a minimum, i believe that the specific number depends on the chip quality (being more or less prone to overheating) some chips can run faster than others, but even tho "lowest quality" chips will meet or exceed the minimum hash rate)

that said, they are currently shipping orders from June 2012... (except the 5gh/s miners which currently shipping orders from oct 2012) they have a lot to catch up on. supposedly everything ordered so far should be shipped by the end of September iirc... but if u just ordered yours then it wouldn't surprise me if it was Oct or Nov when u actually get your unit. BFL is pretty awesome at claiming to be on a certain timeline and then missing it completely.

Actually I'm running the jalapeno (the low end entry) from BFL. I did pay for the upgrade as well. So I should be running at 6.5 GH minimum. Instead I'm getting 7.45 GH. Admittedly it runs a touch hot for my taste (averaging around 46-50 celsius depending on ambient temp. in room) but if the 50 GH model were to show a similar increase over its minimum hashrate claimed it would be running around 53 GH/sec.

Using CGminer and running it off of a raspberry pi with a powered USB hub. Nice low energy consumption to keep the jalapeno profitable as difficulty, and network hash rate, rises.

For anyone unaware, Jalapeno is what BFL used to call their entry level miner, now known as the 5 GH miner.

Thralen

ETA: the 6.5 GH figure is taken from the current claim on older orders of the jalapeno doing 4.5 GH, so with the upgrade 6.5 GH/s.
