22.3M is quite completely finished with a lot of the work done by TheJudger.
My reserved exponents will be processed within less than 2 days. @Wayne : What's the next range for TF work ? Thanks.

I've been dreaming of such a "calculator" since I started....I wish I was better at programming; and math; and time management. LOL I'll need a few days to wrap my head around all of this then I'll try to make some useful comments. Thanks

I don't know if Chris has to make magic or if it will just happen. Thanks

I own a Ryzen 5 3600XT, whose L3 cache is large for a consumer CPU (32 MB) and can actually fit up to DC wavefront FFTs. So I stick to one worker because I tend to run DC. I recently did an informal "benchmark" with some of my DC work (59 to 61 M exponents) and 2 workers * 3 threads indeed performed significantly worse than 1 worker * 6 threads. 3 workers * 2 threads made up some ground, but not all of it. I will have to reevaluate after the DC wavefront advances a bit (say to 70 M). Quote:
A nitpick: GPU factoring programs have had the effect of 3 or 4 more bit levels for almost all prePRP TF, but the "official" TF level where an exponent is cleared for PRP has still not changed from when factoring was done by CPU. Put differently, an exponent of 332,xxx,xxx (for example) will be TFed to at least 81 bits as long as someone from GPU72 can get to it, but if this does not happen then the server will not hold up the PRP assignment.

When I first got this new 7820x PC I was doing P1 from 40M to 50M. 1 Worker x 8 Cores performed the best. Yet my quads i53570 with the same range still perform P1 the fastest with 4 Workers x 1 Core. I actually haven't rechecked now that I am in the 20M to 30M range. Quote:

I'm taking 24.7M next
I expect to start Monday.

Sorry but the following sounds pretty disjoint ... I've always wished I could find an Excel formula to calculate the factor ratio difference with a given B1/B2. (Yes I use Excel ... fossil as it is) I've tried to convert prob.php to an excel macro but it was above me. I would love a dummydowned version of prob.php that I could use as a function/formula in Excel ... for my purposes here it wouldn't have to be exact. A few observations from my experience over the last 4 years I don't think you will get 28 factors going to 73 bits. I know the PrimeNet math suggests so but I suspect that is based on NO P1. With all the big factoring done recently in the 2x.xM ranges I've been seeing closer to 24 per range where there is low to moderate current P1 done. It would be great if these was a tool similar to prob.php that could calculate the expected TF success rate based on how much P1 (or ECM) has been done. To take the entire 17.0 range to 77 bits is about 3.75M GhzDays. or 2.3 years with my 2080Ti GPU. If I were to take all exponents to the highest Bounds above and run this on my 5 home CPUs it would take me about 270 days. So if I was tasked to complete 17.0 with the hardware I have I would do a little more TF but rely mostly on P1. At the individual level, I guess that is what each of us might want to do if they adopt a range:  Use your tool to calculate the TF vs P1 effort as above.  Consider what hardware they own and use it appropriately But at a grander scale for this project it is always a balancing act considering how much TF vs P1 power is available. And that has changed dramatically month to month. I have not much of a clue what the current total capacities are for TF and P1. But if I did your tool is great to use to suggest/recommend TF levels for each range vs P1 bounds. Thanks again Wayne
