Here is the first prime for k=679 for either the Riesel or Proth side since n=155K!:

679*2^539605-1 is prime :smile:

For an average weight k, it was definitely due! I know, I know, mathematically there's no such thing as 'due' but like 18 reds in a row at roulette that I actually saw this weekend, black was definitely due! (lol)
