In case anyone wants a reference point, my dual-core 3800 (which is #2) is running at 2.7GHz so thats why I can pull 700+. A single core 3000+ would have to literally be running 5GHz to have a RAC of 670.

Well you have one thing right... the RAC here is useless... it should be a representation of what a user is doing "recently"

I think I'll see how long it takes mine to go back to zero.

My quick reply (correct or not) would be that the overall account's RAC is averaged over a shorter period of time than an individual computer's. If your computer is averaged over a month, and your account over a week, the former will raise and lower more slowly.

That sounds about like it to me, although it still makes no sense why the two would have a different time period. :)

OH.... and the #1 & #3 Top computers (based on RAC) are still bogus. And #2 is the real deal. :p

Well that formula is good to see. But that still doesn't explain how an account's RAC can be lower than 1 computer on that account.

I see you have three computers attached and basically the simplest answer is the RAC is an average of the three. Your one PC with the 700 RAC is being brought down by the other 2 computers you have attached to the project with much lower RAC's when it averages out the numbers.

(edit)I was incorrect in some respect in how I put it. The average of the 3 computers is also related to how often they report in work. Paul's site states the easiest way to think of it is as a speedometer of how fast your putting out work and the average of your 3 computers is around 300 (/edit)


Any other BOINC project I've paticipated in was simply the RAC of each computer added together... if I have 3 computers and they all has a RAC of 300 then my RAC is 900. I'm utterly confused.

First, obviously I "have a dog in this fight" but this isn't possible :) :


Secondly, how is the RAC figured, since I have on computer that has a RAC by itself of 700, yet I'm only at 300.

Thanks in advance.
