No matter how you slice it, one can not say Broxton's velocity increased over the season. It was not substantially different in October than it was in April. He actually had three months during that span where his raw average velocity was actually lower than his velocity in April. His velocity did not increase as his season progressed. Its just not a narrative that stands the test of tables of velocity. What one is seeing above is the effect randomness.
If one wants to claim he got stronger and added velocity and thus become more effective by the end of the season then they have to claim his spring training data is completely trustworthy and they also have to argue that he got weaker and lost velocity during significant stretches of the season, one of which being his September, the best 13 innings of his season.
Or one could see the numbers for what they are....essentially similar.

This is the blueprint for how a baseball organization should be run. And, whether the baseball men of the 20th century like it or not, this is where baseball is going."---Dave Cameron, U.S.S. Mariner
