Reserving R301 as new

[QUOTE]Reserving R301 as new [/QUOTE]I think I can honestly say that R301 will take you the better part of 6
months or longer. I started S51 over 13 months ago with a ck of 5,183,582 and I'm no where near done with it. I'm still testing around the n=17K range (going to n=25K).
