And the difference between 35 and 40 W is so small as to be irrelevant too I

You've got to be kidding.
It's huge the difference.

15% is a huge lie on something so simple to calculate.

As I said. Tiny. Not even a factor of 2 (that engineers routinely use), let
alone a factor of 10 (that starts to make things interesting).
