Post S287

S287 fully tested n=75-80k
PFGW version 3.7.7

Primes found for 3k's:
4396*287^75164+1
7024*287^79246+1
2044*287^79614+1

96 k's remain.
Testing continues to n=100k

For 75k<n<100k using P1e6 weight I calculated:
k=2044 had 3.42% chance of prime, so I found 12th hardest k remaining
k=4396 had 7.25% chance of prime, so I found 68th hardest k remaining
k=7024 had 8.29% chance of prime, so I found 82nd hardest k remaining

To compare with:
k=5690 has 14.32% chance of prime, easiest k remaining
k=1658 has 1.63% chance of prime, hardest k remaining

Looking at all the k's I would expect to find 4.93 on average in remaining range, 80k<n<100k.
