SomethingÂ´s fishy with the numbers:
The total number of prime exponents below 1G doesnÂ´t match the known number of 50847534. If you take data from 1 day prior, both the number of factored and unfactored exponents appear in green. Most of the progress done yesterday on the 17M range is not reflected in the table.

OK, I think I finally grasp where the problem is coming from. In short it's related to the recent (unrelated) problems with data imports and such that caused the visualization stats for a given date (between Apr 1621) to be rebuilt several times, and due to my SPE could result in exponents being doublecounted if a bit range was completed between the first and subsequent data snapshots.
Assuming that is the problem, I have corrected the source of the problem, and rebuilt data snapshot for Apr 21. If this is indeed the problem then data from Apr 22 onwards should be sane. Thanks for everyone who keeps an eye on these things for me and points out when I break things.

Hey James, the graphic called "Known factor bit depths (0999M)", is indeed to 999M? Or it is to 1G and it is just misnomed?

I have adjusted the links on the site menu to be a little more descriptive (and precise, for the pedants ).

TF Success Stats Latency
Hi James
I have been aware of some latency in the propagation of TF success results, often by a day, but before now have not bothered to mention it, since by the next day the statistics seem to be caught up. I'm even more puzzled by statistics today after yesterday lodging not one, but two TF success results. At first I worried that I had an unassigned competitor in the space, but then remembered the prior experience of latency. In particular from https://www.mersenne.ca/status/tf/0/0/4/11800# I see one result to 75 bits from 118000000 to 118099999, but mersenne.org is vacant for such. It's no big deal, but there does seem to be an unwarranted delay in the sequence of processing. My relevant transactions were: M118074599 has a factor: 59851712641103678686393 [TF:75:76*:mfaktc 0.21 barrett76_mul32_gs] found 1 factor for M118074599 from 2^75 to 2^76 (partially tested) [mfaktc 0.21 barrett76_mul32_gs] M118074637 has a factor: 29327686458922061280743 [TF:74:75*:mfaktc 0.21 barrett76_mul32_gs] found 1 factor for M118074637 from 2^74 to 2^75 (partially tested) [mfaktc 0.21 barrett76_mul32_gs] P.S. From my distance, it seems to me that results have been accumulated to TF slots despite the imperative that the slot needs to be resigned as TF Factor found.

There are multiple levels of latency, depending exactly what you're looking at. A factor reported to mersenne.org will be bundled up (at midnight UTC) and imported to mersenne.ca (approximately 3 hours later). And then various reports and such need to be rebuilt after that. So it can potentially be anywhere from maybe 4 to 29 hours between reporting a factor and seeing it reflected on mersenne.ca
Looking at your two examples, I don't see anything unusual: https://mersenne.ca/M118074599 vs 118074599 https://mersenne.ca/M118074637 vs 118074637 You reported both factors right at the last possible minute (literally  20200527T23:59:12) so they were included in the 20200527 data bundle produced a couple minutes later, and imported into mersenne.ca a few hours later. However, your post (if I read the forum dates/times correctly) was about 2 hours before the data would have appeared on mersenne.ca The TF status report is also rebuilt once per day. Looking at the database right now there one exponent at 75 in 118.0M range is no longer there (the other 52 in the 118M range are). Possibly it's an exponent that you were working on and since your submissions appear to have been right around midnight UTC it's possible that exponent's data hadn't been processed at the time of the report cutoff. With the latency it's inevitable that something will always be "off", and fix itself by the next update (by which time, of course, something else will be "off").

Maybe there is an argument that sustains some merit in retaining a factored result outside the Factored column for an extra day, as if to expose it? Yet if that were not a deliberate intention, that is the behaviour that I'm referring to.

Nothing is deliberately "delayed". What you see is the data as it existed on PrimeNet as of the date shown at the top of the report. If you want to see how the most recent data compares with the previous day's data, the comparison report is available.

If I read you properly, there would appear to be a day delay in the transfer of material particularly factor found from mersenne.org to .ca.
Definitely there is a day of delay from a factor found result being issued compared to being retired to the factor found column, by one means or other.
