Weird GhzD for TF
See attached screenshot for M30759907.
300M GhzD for a 2006 TF effort? EDIT: Ah, I think I see what happened. Composite factor submitted and user got TF credit for unfactored composite. Last fiddled with by James Heinrich on 20220511 at 00:26 Reason: link exponent to site

I have edited the 2006 record to show two prime factors found instead of the composite for clarity.
We're not even certain that this was a TF effort (such detail was not recorded back then) but it seems likely given the size of the factors. Odd though that he found the alreadyknown 68.1bit factor, discovered a new 69.6bit factor, but missed the 68.6bit factor you just discovered (16 years later). I have also backdated the discovery date of the 69.6bit factor from 20080305 to 20061001 Last fiddled with by James Heinrich on 20220511 at 00:48

Considering the fact that a) TF doesn't find composite factors (outside the bit depth), b) the factors are P1 smooth, and c) missed another factor in the range, this is almost certainly a P1 find.

I think (but I could be mistaken) that Prime95 may report a composite TF factor if it finds multiple TF factors under certain circumstances (same class, perhaps?). A rare occurrence at best, of course.
I agree, and have adjusted accordingly.

Can the worktodo balancer be extended to general PRP tests to?
Someone was asking for a script to produce worktodo sections, I pointed to your balancer. They said it did not work for things like: PRP=718849,2,1564054,1 I verified it and tried with an "N/A," added in.

Not that I'm aware of. I am aware of one condition under which it outputs composite factor, which is when the composite factor is of the correct size. Eg: Suppose a number has a 35bit and 40bit factor. Then their product would be either 74 or 75bit. Accordingly, TF from 7374 (resp. 7475) will find the composite factor and report it. This can happen for mfaktx as well. Otherwise, these programs outputs one line per factor even if there are multiple found during a class.

PRP=[AID,]k,b,n,c[,how_far_factored,tests_saved[,base,residue_type]][,known_factors] But it currently expects only k=1,b=2,c=1 I can easily make it accept other values but the GHzdays for the assignment would be calculated as if k=1,b=2,c=1. If all the assignments use the same values then it's probably not an issue, otherwise the "balancing" part would likely be wrong.

You can also look at the list by user and by year, and see that both LaurV and George have missed a P1 factor.
