4.5M however if i divide it by the last prime found n=3140225

Then 4.5 / 3.14 = (roughly) 1.43x

Knowing it used to produce on average each factor 1.2 a prime, and not seldom 2 hide nearby, i hope that it still keeps going at 1.2x by then :)

Do not forget however how lucky i was when i started the formula, finding 3 primes and all 3 were at the start of a range of 1000 exponents that each core processes :)
