I had back then anticipated generating in the time interval (to reach #40) some 27 new PRPs worth about .01 each. Instead, I have to date discovered only 15 new PRPs, but 11 of these are greater than 83000 decimal digits — worth about .02 each, thus the time discrepancy. The road ahead is pictured above. I have taken it as far as #28, Norbert Schneider. I know Norbert because he is searching for the same type of PRPs (Leyland primes) that have created the bulk of

*my*production score, but he has been doing this for much longer. He searches for other types of primes as well and is quite active, so when I take another leaderboard snapshot in a year or two I somewhat expect his score to have kept pace with mine. The caveat being that the algorithm that creates the production score is not the simple additive procedure I have made it out to be and Norbert's score may be weighed down by the larger number of smaller primes that he has over time accumulated.
