They didn't say the 1300 figure was people hours, they just said hours. So for each of those hours you probably much more people hours.

Excellent point. I bet we (many of us professional software developers) are so used to the concept of man-hours that we may be grossly misinterpreting the 1300 hours figure. It could well be up to 1300 times 30 people.

Spreading 1300 manhours for 30 people over 22 months seems a bit thinly spread as well, if you ask me.
