Re: [8500 GH/s] Slush's Pool (mining.bitcoin.cz); TX FEES + UserDiff; ASIC tested
just got back home and checked what the morning CPU mining did... total of 7 shares found, dificulty 1 ( max of 1.1MHash/sec when firefox is closed etc ) and find the following block is calculated ( and time showing last 2 of them were at end of round )
17791 2013-05-01 20:01:25 5:00:24 36782329 7 0.00000000 234096 25.58139100
normaly i'd shrug it off due to the over 36 million shares, this time i know at least 2 shares were in the last few min of the round

Unfortunally for such long round you probably need last minute not last minutes at that speed...
i'd believe most of the advice and as I have previously stated ( somewhere in this thread ) getting 0E-8 is my ' usual ' for CPU mining.
That said, in another round i get the following.
17795 2013-05-01 23:34:54 0:26:48 3199350 1 0.00000002 234122 25.10240000
For the duration/shares versus timing of the share, it seems that there is something wrong with the system since DDos attacks.
I am not crying ' boo hoo, 7 shares and got squat ', to the contrary, i'm saying i KNOW i got 2 in the last 10 min of a round and got squat and not like the newly mentioned payout for only 1 share on a short round. I also recommend for those that can LOG when/how many shares to do so and start looking at the timing of the depreciation of shares per round as I suspect that is the issue.
If I find more like this, I will not be posting it here, i'll be sending the info to Slush. I ask you do the same.
This all could still be fallout from the attack and I do not mind the 10% Slush gets when I use GETWORK. I do however mind if there is something wrong and no one looks in to it to see if they also are experiencing the issue so it can be looked at properly. I never did say how many PCs i got CPU mining, just that I do CPU mining currently.
Guys - I just did a quick check to see if I should be complaining of the way shares are calculated or not .. and got an unexpected result - see below
The "non-exp value" column was just a straight %-based calculation (my % of shares as part of the total - 2% fee). For the record - my average hash rate is around 900MH/s.
(PM me if you want the raw .xls file)

So although on a few rounds I was significantly towards the losing end, it seems the rounds where I was closer to the winning end not only compensated but actually I'm at a 1.19% bonus
I'll be curious to see how others compare - if anyone else wants to do a similar check and share the results.
