That's a very useful doc you have established - hopefully you will keep it updated moving forward! Anyway, based on your info, I just changed my setup to 50% f2 pool and 50% BTCchina pool. I will post my results here when they are in. Keep in mind that you can only change your pool setup ONCE EVERY 24 HOURS, so change wisely. Thanks for the info and keep up the good work scrypt!  =)
