Well it depends, I think on some smaller systems that they happen to have in stock, they could recognize the revenue in under a month. They talked about lead time in the last conference call.
Also, don’t complain about finally having a backlog number, no matter what spin comes with it. Other than sporadic PRs and usaspending/govtribe it’s the first thing we’ve ever had to find out forward revenue. It’s also very common to list a backlog that isn’t all recognized in a year yet still say revenue will be up based on backlog. I’m invested in another company that has like a $2 billion backlog yet only does $800 million a year in revenue and can say revenue will go up this year. It’s nice because you know they at least have good revenue out two years, and they are also in a lumpy business.
