Thus all we can conclude is that the energy per instruction lies somewhere between 0.65/115.5e9 and 0.75/114.5 pJ, or between 5.6pJ and 6.6pJ.

IOW, there's a good chance that not even the first digit you quote is correct. Why, then, do you state nine digits? That amount of precision is total BS.
partly because I was typing it from a calculator. also I think you'll find that based on your own calculations, that 6 shows as the first digit in your range about 7 out of 11 times.
