Obviously, it has to do with what you've accomplished on your computer with PrimeGrid. For example mine says "Work done for this project: 32,934". But what does that mean? 33,000 what? In what units is it measuring in?

I downloaded BOINC yesterday so please excuse my lack of knowlegde

Hi there and welcome.

I assume you are referring to Account certificate at https://www.primegrid.com/cert1.php

BOINC credit, or it's units in Cobblestones, are units of performace.
t is a way to compare how much work each participant or computer has provided.


Computation credit.
A BOINC project gives you credit for the computations your computers perform for it. BOINC's unit of credit, the Cobblestone (named after Jeff Cobb of SETI@home), is 1/200 day of CPU time on a reference computer that does 1,000 MFLOPS based on the Whetstone benchmark

Here on primegrid, we also have Badges for each respective subproject that represent how much work was done.
____________
My stats
Badge score: 1*1 + 5*1 + 8*3 + 9*11 + 10*1 + 11*1 + 12*3 = 186

One more thing each Boinc Project has their own amount of Cobblestones they award us for the work done for them. Meaning Project A will give you X amount of Cobblestones/Credits for each workunit you finish and gets validated while Project B will award Y Cobblestones for the same amount of work on it's workunits. What that means is only compare Cobblestones/credits within a Project or sub-project not from one Boinc Project to another.

Credits/Cobblestones can be a way of enticing people to crunch here or there so if one Project wants lots of people they may award 100 times as many Credits for the same amount of work that another Project will. One billion Cobblestones/Credits and $10 will get you a cup of coffee at Starbucks, but without the $10 you are NOT getting that cup of coffee.

Essentially Credits show the commitment a user has to a particular Project, for instance if you look at Honza's numbers they have 2.6 Billion credits and their RAC is1.1 Million. RAC is like a speedometer that adjusts depending on your contribution over the short term.
