I saw the very natural reflex to curb unnecessary precision
which does not contribute to accuracy here.

   But then I had a treacherous thought.
If the suggestion had been couched as
"multiply the resistance by 4/3" the approximate nature
of the suggestion would be clear - yet its decimal equivalent 
seems quite out of place.
   Mallinckrodt has it right of course - just a question of 
saving key strokes.
