Topic 187226
(moderation:
I was just randomly looking around and stumbled on this.
for example under "Steffen Grunewald on behalf of Merlin The Wizard" he has computer id 3657 which shows 13 results with a claimed credit of 524.85 but this computer shows a total credit of 129,899.71 .
another computer that seemed odd is 3832 which shows 22 results with a claimed credit of 761.07
but the computer shows a total credit of 41,948.81. these are only 2 of the computers I looked at but there maybe more.
I just checked my computers stats and all seems normal. This is just an observation not a statment against anyone.

You will only see the results that are currently kept in the database. Once a Result is considered to be over, i.e. the deadline is reached or all sent Results returned and there had been chosen a canonical one, these are subject to be purged from the database and will eventually be deleted. The credit granted for these of course is kept.

Maybe I don't see where you are coming from but the computer in question was only created on 3 Jan 2005 17:39:20 UTC and has only reported 13 Results. Based on average claimed credit per those 13 units it would have taken this computer 3217.24 results to get that total credit. As for the purging of old WU's I looked under my oldest computer and it still shows all 195 results that I got credit for and that goes back to early NOV, and I don't think that it would erase those reults from your result total.
I think there must be some bug in the stats somewhere because it is imposible given the data about said computer in the stats that this machine could have validly gotten that many points.
Here is a link the the computer ID in question

The machine has been merged, so the creation date is the date of the merge or at least the one of the newest machine id of the merge. No need to worry. 3000 Results is not impossible for this machine, it has not been doing much else beside e@h since Steffen got his account. I myself have one running (since Oct 22) that did about 3000 Results and it is by far not exclusively dedicated to e@h.

Well Steffen can speak for himself, but I suspect with the ID of 3647, that he recently detached and re-attached that computer, and then merged the newly created ID with the old. The total results will be for the merged ID's, but the other numbers will only reflect work done by the newest ID.
You will see something similar with my own ID of 2771. That computer actually started crunching on November 8th. Then it was "detached" for a few days and re-added. Since it was the same machine as before, I had the option of merging the new ID with the old (which I did). Now it shows the computer ID created on December 23rd. It shows 119 results but 17,358.9 in total credit. It will also show in the list, pending credit going all the way back to December 17th (which is from the prior ID). That particular box has actually had at least 3 different ID's all of which have been merged into one. It has crunched for all but a few days since November 8th. The current creation date is for the latest ID. I think the original ID was 69x something.
It is not a database error, but simply the result of merging ID's from the same machine, which occurs if you detach and reattach, or sometimes will happen due to a system or work unit problem that causes it to create a new ID. If you merge the old and new ID, they you will see what you are seeing. Merging ID's can only occur though if they are all from the same machine/OS. Change OS, mobo or cpu, and you have a new machine that cannot be merged.

Thanks for clearing up the merge effect.

Yes, I had to restart several machines due to the bad effects of a proxy limiting
uploads to 1MB. And for fun I merged all the machines with the same processor
identification (note that there are TM and tm strings!) into one per type.
Don't worry too much about it. The overall sum would not change. Although I help
to run the project, there's no point in cheating...
Cheers, Steffen
Steffen, I wasn't saying you

Steffen, I wasn't saying you were cheating. I didn't understand the merge and thought the stats pages made an error in generating your stats.
sorry about the confusion,
