Requesting SWAG on what's most likely to score me a Mersenne Prime.
What is more likely to score a prime in a given amount of time, firstpass or doublecheck? (Please note that, for example, if secondpass takes 1/5th as long as firstpass, you need to multiply the odds by 5 in order to respect the "given amount of time" portion of my request.)
I'm more curious than anything else, I don't really expect to find an actual prime.

The firsttime test error rate is in the neighborhood of 23%. So, first time tests are the way to go.
