Yeah well the classical mistake if i may say so. You're plotting a derived function and then based upon the derived function say something about the actual functions.
Much simpler is doing a profile run with the actual code and then for each function in your code, see the direct data, rather than this graph. It's very easy to have the processor execute NOPs of course and then claim a high IPC based upon that.
