Thank you for having provided the relevant information: the number of surviving candidates for a given factoring depth (sieving depth ?). Then the probability of an individual candidate being prime is approximately independent of the Proth weight. I'll make the calculations and confirm or infirm my previous considerations...

We are now listed on Henri and Renaud Lifchitz' page PRP Records with first, second, and fourth places! Our "production score" climbed from 45.70 to 47.76, and the record probable prime I found a year ago is now in seventh place. Go team!

So that is why they call Australia the lucky country. Not just gold mines and sunshine, they have all the big PRPs too :)
Well done again Ben!
