No, there is nothing to do between the numbers and jobs maintained or created. The estimate we have is for the two together. We couldn't make the difference between how much will be created and how much will be maintained. So it's not the source of your puzzle.
There are two sources for your interrogation. One is that we are saying we will create 220,000 jobs by the end of 2010. The idea is to make sure we create some jobs and we keep that level up to the end of 2010. In some sense, we're talking about $100,000 to create or maintain a job. If you use that as a scaler, you need that amount in 2009 and in 2010. You need to create that job and keep that job maintained or created. You need to divide the package by two to start with. The government has a package of 4% of GDP; you need to divide it by two to apply these rules.
It's easy to create a job or maintain a job, but they could disappear very quickly if the money is withdrawn quickly.
