PRP is at 13641092 at the time I started to write this post. Between that value and 14000000 there are 6949 k n pairs. At approximately 100 pairs/day that is 70 days work. glennpat said that he is factoring at approximately 7 pairs/day/core and we know that there are 216 pairs in his interval. Which means that he will finish that interval in 31 days, or less now that he is using two cores.
What we need to worry about is the next interval, and the one after that. To stay ahead of PRP would take 14 or 15 cores running at the same speed as glennpat's machine. Look's like it's time to start P-1 factoring in earnest.
