yes and the sad thing is diff is on pace to be under 10%  third diff jump in a row..

so put 9% in your calc and these roi very nicely.  we are in the summer s-1's are being pulled off line.  and this stops the skyhigh diff jumps.  I am thinking we may go into sept before a jump over 15% happens.  these lower diff jumps will be good to anyone that has some s-3's mining now.  my batch 1's have mined for 10 days already.
