Let's finish DC of old "dubious" claims of primes
Of the roughly 90 "dubious" claims exponents, I have the following as not yet having a factor found, matching DC or TC, or PRP with proof & successful cert.
Code:
PRP=1,2,86225219,1,76,0 PRP=1,2,87232913,1,76,0 PRP=1,2,89023807,1,76,0 PRP=1,2,96532433,1,76,0 PRP=1,2,97970567,1,76,0 PRP=1,2,103404713,1,76,0 PRP=1,2,108575167,1,77,0 PRP=1,2,110000017,1,78,0 PRP=1,2,122628553,1,78,0 PRP=1,2,137362691,1,80,0 PRP=1,2,231695603,1,79,0 PRP=1,2,276036017,1,80,0 PRP=1,2,285754177,1,80,0 PRP=1,2,315690521,1,80,0 PRP=1,2,333333223,1,81,0 PRP=1,2,369452123,1,81,0 PRP=1,2,852348659,1,86,0 Last fiddled with by kriesel on 20211224 at 20:43

Why do these exponents deserve special attention, just because someone made a claim about them? (in other words: don't feed the trolls).

Those from the "Guess Mxx" threads should usually be taken with 10g NaCl crystals.

Overlap is rare.
M852348659 appeared elsewhere and was classified as a dubious claim first, before someone entered it in the predict m52 thread, so it is not counted again in the predict m52 total. I found no other overlap between my dubious claim DC list in post 1 and the predictMxx lists on my server share (M45, M49, M50, M51, M52). Predict Mn guesses are not counted again if reused in Mo (o>n) guesses, in the counts I occasionally update. Quote:

A horse can only be declared lost if the result is a certified composite. In addition, there are barely around 90 of them, not 9,000. Maybe UncWilly should add this rule to the Mxx thread, exponent guesses must not be greater than 4x the size of the exponent of the current largest known Mersenne Prime or 3x the size of the exponent of the current wavefront milestone, whichever one is larger, but it's up to UncWilly to decide. A lot of complains have been generated because someone places down a large guess in the M800M+ or M900M+ ranges which will take around a year or 2 to test the exponent, there can be an easy fix to this. Is this what you've meant the trolls? Last fiddled with by tuckerkao on 20211225 at 03:08

There is no obligation to test exponents the others have suggested. So there are no grounds for complaints IMO.
If you want to test them then go ahead. Else leave it to the person suggesting to test their own exponents. If you don't like the their suggestion then just ignore it and carry on with whatever are your own preferred exponents.

Updated list
Most of these I did a first test on, so the server won't issue DC to me.
