BFL has the 40Gh/s system.
BFL takes them seriously, makes a promise to overclock their ASICs by 30%. Raising it to 60 Gh/s.
Last time I checked, overclocking from 40GH/s -> 60GH/s was a 50% overclock, not 30%. I could be wrong tho. Those damn maths are sneaky little bastards.
Your right. I was thinking of the 60Gh/s instead of the old 40Gh/s. I'll go back and change it.
