You had not previously reported a status so you found a lot more primes than that! There were 209 primes found for n=10K-25K so...

To be more specific for balancing purposes:

For R555:
500 k's remained at n=10K
136 k's were found prime for n=10K-25K
364 k's remain at n=25K

For S555:
277 k's remained at n=10K
73 k's were found prime for n=10K-25K
204 k's remain at n=25K

In the future when doing both sides of the same base, please report and send primes and k's remaining split up between Riesel and Sierp. It took me a while to split them all up and balance them. Thanks.
