What I'm saying is that if p is prime, the best estimate that Mp is prime is
2.5695 * log(ap)/p, where a=6 if p == 1 mod 4, a = 2 if p == 3 mod 4. For
example, for exponents around 7,000,000 this gives probabilities of 6.44E-6 and
6.04E-6 respectively, or 1/155200 and 1/165600. The figures that Status gives
for the exponents I'm working on are precisely a factor of 'e' higher.
