Oh, OK. I'll take a look at those links later today. Your percentages are in line with what I would expect. We have an "odds of prime" spreadsheet with formulas created by one of the math experts here. I'll check them against that.

I think I misunderstood you previously. With this statement:

Quote:
R620 has the highest chance, 11.42%
I thought you were looking for the 1k base with the largest chance of finding a prime by n=200K. But with these statements:

Quote:
If you test R702 to 200k the chance of finding a prime and so proving the conjecture is 14.12%.
If you test R916 to 200k the chance of finding a prime and so proving the conjecture is 13.43%.
You seem to have concluded otherwise.

So we are in agreement that R702 and R916 have a better chance of prime by n=200K.

Regardless it doesn't matter to us what base you test. I just wanted you to realize that there are bases with a better chance of prime by n=200K than the one that you chose.
