BFL are not claiming they have shipped 90 Th/s in the past 10 working days. You are the one making that claim.
So, did you actually read the article linked in the OP? Is the author lying?
“We’re shipping about 300 units a day, but we’d like to be doing more”, Butterfly Labs Chief Operating Officer Josh Zerlan tells me.

That author visited BFL during the time when BFL "stopped the Jalapeno line to let the Singles and Mini-rigs catch up".
So yeah, BFL is claiming to have shipped 90TH/s by virtue of claiming to be shipping 300 little singles (or better) a day.
Let me provide the entire quote from the article from the OP:
"The Butterfly Labs HQ is bustling with employees, over 35 of them I’m told. Customer service, assembly and logistics are all run from the facility.
“We’re shipping about 300 units a day, but we’d like to be doing more”, Butterfly Labs Chief Operating Officer Josh Zerlan tells me. We’re standing in the back of their facility in a suburb south of Kansas City. This is the warehouse portion of their headquarters, and it is chock full of boxes from floor to ceiling. A forklift is parked off to the side."
Like I said, and as you have just shown, BFL never claimed to have shipped 90 TH/s in 10 days.
