Default Calculating optimal P-1 memory

I searched around a while back and did not see an answer for this...

I know that the more memory that can be given to P-1 stage 2, the better. What I was trying to figure or find, is there a formula or tool somewhere to: calculate how many relative primes P-1 will process for a given set of parameters. On one machine I noticed that if I went from one amount of memory to another the number of primes jumped disproportionately. I would love to find out where the various break points are for various assignments. Then I could tune memory settings to be livable and productive. Also, if I knew that I could add 50 or 100 MB to the night setting and get a boost in the number of primes, that would be great.
