How is changing a number fudging the science? Dude just liked powers of 2 so he set arbitrary things to be slightly different numbers. Heck, even Celsius is pretty arbitrary. The triple point of Hydrogen Hydroxide isn’t actually some magical mystical temperature that’s more important than all other temperatures, and the boiling point of one particular chemical at our best estimate of the average atmospheric pressure on the surface of this one particular rock is almost completely meaningless.
