I've read numerous threads on here regarding all of the issues/concerns about PRPNet credit, as well as how it transfers to PSA credit. But, I just have a question regarding PRPNet credit specifically, and I apologize if this isn't the correct place for this, hopefully someone could point me in the correct direction then.

I am more curious about the differences in credit between the different ports. I know they were always slightly different and some ports seemed to give a little more "bang for the buck" but most recently I've noticed some extreme discrepancies.

I currently run 3 machines and between them 16 roughly equal cores. (12 are in fact indentical as they are same build machines) Recently I ran several days on the 27 port, and seemed very happy with the results. Running 24/7 with my cores I was able to produce around 900,000 PRPNet credit per day.
Well since then this week, for the last 3 days or so I have moved over to the FPS port, where it seems I'm averaging out to around 90,000 PRPNet credit per day. A factor of 10 difference just seems a bit extreme.

Not sure what is right or wrong, but I'm just more curious how/why the discrepancy.

The FPS WUs seem to take much much longer to crunch than the 27 WUs, yet yield significantly less credit. Looking at the size of the numbers being tested, it appears (i may be mistaken) that the FPS numbers are significantly larger right now too, which helps explain the increased processing time.

Thank you in advance for any explanation. I'm always curious and like to understand how it all works. I'm here more to just contribute to all of the projects than to collect credits, but they are a nice reward on the side. :-)

While I understand all of that, and see how its good way to compare results within a project/port, i guess my concern then does go back to an assumption I had, which relates closely to several other peoples concerns in regard to PRPNet credit conversion to PSA credit.

I guess from what I've read, and witnessed first hand, I've always seen its roughly 18:1 conversion rate. So based on the assumption of a fairly constant conversion rate, I felt it is valid to compare how credit is given between projects.

Or is my assumption on a constant conversion mistaken as well?

I guess using the example from my first post, in the end, does a full days worth of effort on the 27 port, equate in PSA credit closely to a full days worth of effort on the FPS port?

That's a good question because I've been told that the ppselow port moves credit over to psa at a 20:1 ratio not the 18:1. I'd always assumed that the credit was moved based on total accumulated but now I'm also wondering if psa credit is moved at ratios based on ports worked.

I have never understood the conversion as 105,264,010 overall(ancient, active, overall) translates to 4,593,953 for me at least.

Close enough I guess :)

Today my PSA credits rise from 4500 to around 6650. But that is far below current PRPNet credits

Yesterday I have 2,866,075 PRPNet points...
You give me around 1800 PSA credits
