The chance that a wrong LL residue is found is eventually 100%, the chance that a wrong P1 result is smoked out is only a few percent at most. Worse, a wrong dedicated P1 machine can produce a lot of wrong results in little time.

That is probably down too much since not all exponents posted in this thread made it to the list. Also, I don't know how often the listed is updated, but a new exponent I found today and added to the mersenne v5 server did not yet pop up in the list after a few hours. That exponent is http://www.mersenne.ca/exponent/12526721.

The list is updated once per day, roughly 11pm Eastern time.
If you notice a particular exponent that should be on the list but isn't, and the factor you found was reported to mersenne.org more than 24h ago, please let me know.

Notice that the biggest factor in http://www.mersenne.ca/exponent/48152443 is the product of the first three factors.

I think you're looking at the composite factors, which are just all combinations of any number of prime factors. One such combination is all three prime factors.

3 more factors that I believe should be on the list

Please consider that in cases (2) and (3) the original lower B1/B2's appear to have been overwritten with new larger values. Just in case, I've some saved data from midDecember, to corroborate this. HTH ric

I'm not terribly concerned about the missing data. If George wants to dig up the ancient v4 database and pass the submission logs my way I could in theory parse it all and extract the original P1 submissions, but beyond that it's just a fuzzy memory that (in my opinion) can stay that way.

Red herrings?
Neither am I, given their zero contribution to overall workload reduction  just wanted to draw attention to the fact that those 3 numbers were treated in three different ways by mersenne.ca update scripts:
