The MIPS data looks suspect.  How many times was the program run, and
what were the standard deviations for these measurements?

If, as it appears, you ran the MIPS job only once, you don't have
enough precision to draw the conclusions you did.  And even if these
figures are precise, to derive a seven-digit number like 1,400,083 from
two-digit numbers seems a little silly.
