Default Some results on S{250..255}

These are A-side 14e, A-side 15e, R-side 14e, R-side 15e timings for a number of candidate numbers, with 31-bit large primes. These are pretty clearly 15e numbers, though may need a little more ECM before queue submission.

130.87 yields with 3 large primes (A3.0 => lss=0, 3 large primes on A side); 15e, 31LP
Code:
A3.0	y=7823	t=1.229s/r
A3.1	y=7503	t=1.302s/r
R3.0	y=8140	t=1.229s/r
R3.1	y=6874	t=1.295s/r
so that's a significant disadvantage over 2 large primes
