First of all, we don't supervise the work. As a prime contractor or prime vendor, you're responsible for nothing to do with project management and nothing to do with budget management.
I don't have the exact number, but if you were to take the 23 resources working on the project and times that by two years, that would give you the days or hours that were put toward it.
I think I remember from somebody's testimony that there were 8,200 days. If you were to divide that by just 16 resources, not the 23, that still returns less than two years' worth of work per resource.
