OK I'll start testing within a couple of days for n=300k-500k. Thanks.

k=32767:

This one is currently reserved by Diep for n=5M-30M. Since it is so low weight I thought it would be interesting to see if there were any more primes up to n=1M.

Double-check complete to n=50K. 4 previously found primes confirmed. No problems found.

First-time check complete for n=50K-1M. No primes found.

This is a very low-weight k! :-)

Results attached.

k=10005 has a large prime gap so I double-checked it for n=0-1.25M.

34 primes confirmed; no problems found.

Results attached.

I've completed the remaining RPS 9th and 10th Drive k's with missing ranges from n=350k to 375k. 21 primes were found, which are attached. Of the laptops mentioned in my last post on this set of k's, the Kubuntu Focus has been dedicated to GIMPS and is not working on this project, but the older laptop is actively working on this. The expected finish date is currently October, though I may dedicate some additional cycles to it once it gets closer to the finish line.
