After the explosion it was flat compared to the explosion year. But the increase from FY 2008 through FY 2015 includes the last pre-explosion year. At least that’s what I think I figured. If I remember correctly what I looked at, the pre-explosion year compared to the 1st year with a significant increase was around 27% higher over a 7 year period.

Corrected. Total outlays FY 2008 were $2,982B. Projected FY 2014 is $3,618B, increase of $636B or 21.32% of $2,982. Divided by 6 years is 3.55% average increase over the 6 year period.
