Assuming that the August exponent is just a little smaller: Would the usage of an unnecessarily large FFT for this one explain the speedup for the September exponent?

That's not necessarily true. "Finding 12 World Record Primes" is more convenient to write than "Finding 11 world record primes and one almost-world record prime because we found it out of sequence."

Yes indeed, more convenient but less truthful. So can we assume the current banner (12 W.R.P's) is in fact the truth? After all, would GW lie about this sort of thing? Or can the "truth" be stretched to say that with just a few days between discoveries we can use a bit of artistic license and say that they were discovered together?

It would be nice if "M46" was M43041727, though. TPR would have finally found a prime after so many years!

Sergey Bubka would disagree. That's why he always added just 1cm to his previous record. Even if he passed (many of) his marks with a foot margin.

What good is it to jump 25cm higher and then bite the dust for several years? Bolt (I am sure) knew the same and never pushed it beyond a necessary margin for a new record.

I think the fact that all three verifications are quicker for the Sept
prime shows pretty conclusively that it is smaller than the August one.

And Elena Isinbayeva learned the lesson well.

Is there a possibility that M(Sept) is actually M44 ( or lower) then?

My guess is no.

Thanks, no wonder the C64 was not dusted off.

My verification of the Aug23th candidate prime has ended.

As expected, Glucas says (again): NEW MERSENNE PRIME DISCOVERED !!!

Verification of Sept6th is 80% done.

See you later.
